This is a recent QoD FAQ and, although we already list all the hotels that do charge a resort fee (or some equivalent that may go by another name) -- an increasingly inclusive list -- we do understand the usefulness of a thumbnail guide to those exceptions to the rule. Hence here's that list, which we've also now added as an introduction to the page where we list all the hotel resort fees around town, together with a list of the amenities that they cover.
One last point we'll make is that, although we understand how, on principle, some people flatly refuse to pay a mandatory fee in addition to their room charge, if you're going to use any of the standard amenities included and are prepared to keep an open mind, in some instances you may find that it's to your advantage, financially and in terms of convenience, to pay a resort fee. In other cases, of course, it won't be.
Now, here's that promised list, which we verified last week. All are hotel-casinos unless otherwise indicated:
In addition, Treasure Island (TI) and JW Marriott (in Summerlin, by the Rampart casino) charge an optional resort fee -- check what's included and whether it's cheaper for you to pay for amenities à la carte or to pony up for the inclusive resort fee.
