This is a great question, and the basic answer is simple, if not what you likely want to hear. From our experience in talking to friends and associates, and information gleaned from feedback sent to LVA reader polls and our various blogs, the general rule of thumb is that resort fees are still charged even if a room is comped, rendering such offers of "free" nights somewhat disingenuous, although it could be argued that you are receiving a free room, while still being required to pay for the extra resort "amenities" that you may or may not use. If you're paying $12.95, or even $25, for a room that has a current rack rate of $120, for example, then it's still a darn good deal. Hence, it might pay dividends psychologically to look past the PR-speak and semantics and, rather than getting hung up on the fact that you're paying a minimal fee for things you don't want and/or an allegedly "free" offer, adopt a "glass-half-full" mentality and look at it as a really cheap rate for a great room that you could not ordinarily have hoped to book by any other means.
Another important point to bear in mind is that while we just stated that resort fees attached to comped rooms are the norm, this policy is consistent only in its inconsistencies, since there is often no official written-in-stone law and the discretion of your host/concierge frequently comes into play. As Jean Scott wrote in her Frugal Vegas blog post on the subject, way back in 2010:
"Unfortunately there is no one general casino policy on this. In fact, the answer may not be the same from one visit to the next at the same casino. You will need to ask each and every time you make a reservation and verify when you check in.
"This is one area where a host can often make fees disappear if you have given some substantial play. Even if you are paying for your room, you could ask your host – nicely – if you 'qualify' for having the resort fee taken off your bill. As the famous saying goes: 'It never hurts to ask!'
"One last tip: There is often a disconnect between casino departments and even if you have been told there will not be a resort fee added, it may mysteriously make its way onto your hotel bill. So, a good rule of thumb is to always check your bill BEFORE you leave. It is much easier to get it corrected then than after you get home and check your credit card charges."
That's all true and sound advice and the "Queen of Comps" received some sensible, sanguine responses from some of her readers, such as:
Another respondent commented:
And here's some feedback in a similar vein that we've received in response to various LVA Reader Polls on the subject of resort fees and comps:
That's what we mean about being stoical as opposed to hysterical about these surcharges, which are now so widespread -- having infiltrated both downtown and the 'burbs -- that it's virtually impossible to avoid them. Properties like Treasure Island and the J.W. Marriott in Summerlin seemed to blaze a promising trail with their experimentation with optional resort fees, offering guests the choice of a discounted package of amenities versus the ability to pay for individual elements on an à la carte basis. We had high hopes for this kind of program, which seemed like the fairest approach, but both hotels have since discontinued this option, so evidently it didn't work out as they'd hoped, for some reason. However, as a couple of people have indicated, sometimes the "squeaky-wheel" approach works, and if you query/complain about the fee, you might just get it waived.
As to one specific exception to the rule that we know about, if you are a Diamond or 7 Stars member of Caesars Entertainment's Total Rewards program, you don't have to pay a resort fee at any of their Las Vegas properties.
Meanwhile, we just this week updated all of our Las Vegas hotel resort fee listings, there having been many movings and shakings afoot of late. Some are up (e.g., Bally's, Circus Circus, Downtown Grand, Harrah's, Paris, Planet Hollywood, Plaza, Silverton, Stratosphere), one is down (J.W. Marriott), and some amenities have been added here and there (e.g., Downtown Grand's now includes self parking, valet, and pool access, Excalibur recently added a $20 dining credit, Flamingo and Planet Ho include Internet access for two devices, not just one, and Palace Station now offers a shuttle service to the airport), while others have been subtracted (no more in-suite private-label coffee at Signature, while El Cortez has substituted a bottle of wine in The Flame for a glass of wine or draft beer in Cafe Cortez and no longer offers free access to the daily slot tournament.) The bottom line is, as we say in the U.K., "you pays your money and you takes your choice" (so make sure you're well-informed when you make it by checking out that last link.)
