Las Vegas hotels have raised resort fees. On some nights, expect to pay more in fees than the cost of the room.

Las Vegas hotel-casinos have raised resort fees that are automatically tacked on to the cost of your room. On certain nights, visitors could pay more in fees than the cost of a night’s stay.

Last Thursday, Caesars Entertainment raised nightly resort fees up to $5 at eight of its nine properties in the city.

Here’s how much you can expect to pay:

Bally’s, Flamingo, Harrah’s and The Linq: $35 (up from $30);

Cromwell, Paris and Planet Hollywood: $37 (up from $35);

Caesars Palace: $39 (up from $35); and

No change at Rio, which charges $30.

Fees at other hotel-casinos have gone up too. Nightly fees at MGM Resorts properties range from $30 at Excalibur and Monte Carlo to $39 at Aria, Bellagio and Vdara.

Two Wynn hotels as well as at The Palazzo and The Venetian charge $39 resort fees..

How can a resort fee double the cost of your room? The Caesars.com website shows Harrah’s offers rooms for $29 on Monday night and $28 on Tuesday — prices lower than the $35 nightly resort fee.

On five weeknights in February, rooms at Bally’s start at $30 a night, $5 less than the nightly resort fee. At Rio, rooms cost $29 on six week nights this month, $1 lower than the $30 fee.

At Circus Circus, one of MGM Resorts’ properties, room prices on 17 of the remaining 24 days this month cost $20 or $22, less than the hotel’s $29 resort fee.

Resort fees typically cover in-room Wi-Fi and local phone calls, as well access to fitness centers and swimming pools. Of course, the fee is charged whether you use the amenities or not.

To find the full cost of your Las Vegas hotel room, add on fees and the 13.35% hotel tax charged by Clark County, which is where Vegas is located.
