A hotel room can look like a bargain when you first book it. Then checkout rolls around, and the final bill is suddenly much higher because of parking, resort fees, Wi-Fi, minibar charges, and other extras you may not have expected.

Some hotel fees are unavoidable, while others come from services or items you may not realize cost extra. A little planning before your stay can help you spot these charges before they turn into an unpleasant surprise.

Here are 15 hotel charges to watch for before you book or check out.

Bottled Water and Snacks

That bottle of water sitting on the desk may look like a welcome treat, but it can come with a surprisingly high price tag. The same goes for snacks, coffee pods, and drinks placed around the room.

Before opening anything, check the room’s price list or ask the front desk. A bottle of water that looks harmless can turn into a $6 charge on your bill.

Resort Fees

Resort fees are one of the most frustrating charges for travelers. Hotels may add them each night to cover things such as pool access, gym use, towels, Wi-Fi, business centers, or local phone calls.

The problem is that you may have to pay the fee whether or not you use the amenities. A room advertised at $129 a night can cost much more after a $30 or $50 daily resort fee is added.

Destination or Facility Fees

Some hotels use terms such as “destination fee,” “urban fee,” “amenity fee,” or “facility fee” instead of calling it a resort fee. The services covered can be similar, including Wi-Fi, bottled water, fitness facilities, or local perks.

These fees aren’t limited to beach resorts. City hotels may add them too, so check the full price before booking instead of looking only at the advertised nightly rate.

Parking Fees

Parking can add a serious amount to the cost of a hotel stay, particularly in downtown areas, beach towns, and popular tourist destinations. Self-parking might cost $25 or $40 a night, while valet parking can cost even more.

Check the hotel’s parking policy before you book. A room with a slightly higher nightly rate may actually be cheaper once parking is factored in.

Early Check-In Fees

Getting into your room early isn’t always free. Some hotels will let you check in early if your room is ready, while others charge a fee for the privilege.

If your flight arrives hours before the hotel’s standard check-in time, call ahead and ask about your options. You might be able to arrange early access without paying extra, but don’t assume it will be included.

Late Checkout Fees

Need an extra hour or two before leaving? That extra time can sometimes come with a charge.

Hotels have to prepare rooms for incoming guests, so late checkout policies vary. If you need more time, ask the front desk before checkout day. Depending on the hotel and your loyalty status, they may give you extra time at no charge.

Wi-Fi Charges

Free Wi-Fi is common, but some hotels still charge for internet access. Others provide basic Wi-Fi for free and charge for faster service.

Check whether the fee applies to the room or each device. A family connecting several phones, tablets, and laptops could end up paying much more than expected.

Minibar Sensor Charges

The minibar can be a trap if you’re unfamiliar with how it works. Some hotel minibars have sensors that automatically register an item when it’s moved.

That means picking up a drink to read the label and putting it back could potentially result in a charge. If you need to move anything to make room for your own food or medication, ask the front desk first.

Taking a quick photo of the minibar when you arrive can also give you a record of what was there.

Housekeeping or Service Charges

Some hotels add housekeeping, gratuity, or service charges directly to the bill. These may appear as daily fees or under a general service charge.

Don’t assume that a service charge is the same thing as a personal tip for your housekeeper. If you want to leave cash for the person cleaning your room, mark it clearly so there’s no confusion.

Airport Shuttle Fees

A hotel airport shuttle may sound like a free perk, but some hotels charge for the service. Others charge per person or per trip, and some require advance reservations.

Before counting on the shuttle, ask about the price and schedule. If several people are traveling together, compare the total shuttle cost with a rideshare or taxi.

Package Holding or Delivery Fees

Shipping a package to your hotel can be convenient, especially during a business trip or longer vacation. It can also come with a handling or storage fee.

Some hotels charge for receiving packages, keeping them at the front desk, or sending them back out. Ask about package policies before sending anything to the property.

Luggage Storage Fees

Many hotels will hold your bags for a few hours after checkout, but that service isn’t always free. Some properties charge per bag, especially in busy tourist areas.

If you have several suitcases or need to leave your bags for most of the day, ask about the fee before checking out. A few dollars per bag can add up quickly.

Credit Card Holds and Deposits

A temporary credit card hold is common at hotels. It may cover potential room charges, damage, minibar purchases, or other incidentals.

The amount held can be much higher than the cost of the room itself. Ask at check-in how much the hotel plans to hold and how long it usually takes for the hold to disappear after checkout.

Cancellation Fees

A cheap hotel rate can become expensive if your plans change. Some bookings allow free cancellation until a certain date, while discounted or prepaid rates may be nonrefundable.

Before booking, check the cancellation deadline and read the rate conditions. Saving $20 on a room isn’t much of a bargain if you later lose the entire booking because your plans changed.

Local Taxes and Tourism Fees

Taxes are part of most hotel bills, but some destinations also add tourism fees, occupancy charges, improvement district fees, or other local surcharges.

Hotels may have little control over these government or local charges, but guests still have to pay them. Check the final booking total rather than comparing rooms based only on the advertised nightly price.

A little extra time spent reviewing the fees before booking can make a big difference. Knowing what you’re actually paying for makes it easier to compare hotels fairly and avoid surprises when the bill arrives.
