For anyone going to the US, beware that their advertised hotel room prices don’t include - OMG. This link might be subscription walled but if you can read it, it demonstrates the lengths of obfuscation out there to get dollars from guests. Whether or not you use them (chain and location dependent) they will add ‘mandatory’ fees for cleaning, room safe, resort amenities, location fees, higher costs of car parks, and for perspective, the high end Regis in New York City has a typical nightly rate of $800, that gets ‘mandatory’ $50 fees on top. None of that includes the myriad taxes America puts on hotels (and rental cars) that are usually in the range of 10-15%, noting in the US it is not on to show tax inclusive pricing.
FWIW wikipedia has a rundown too. It incldues a comparison of practices here, in the US, and the EU.
Some localities add unique local taxes, such as getting rental cars from the airport or nearby locations instead of ‘well away’ from the airport, where the daily cost can be near 50% because of ‘tourist/traveller amenity fees’ applied on/near-airport.
