I very much doubt it will be as high as $x,xxx. Personally I think you would struggle to get $xxx.
CheapHotelResorts would be better, even CheapResortHotels. It is three words, low monthly searches and the double plural just kills it. imho.
The exact monthly global searches for the keywords Cheap Resorts Hotels is "0"
For Cheap Hotel Resorts it is 36.
Add to this the very competitive nature of this niche and you are going to really struggle to get anywhere even with development unless you have a decent budget for marketing/advertising or are very skilled at SEO.
I think you will be lucky to get mid xxx. High x,xxx is abit of a fantasy But you can certainly start at that price and see where you end up. You can target companies with similar names to see if they would want it. The exacts on these keywords are pretty low. Anyway my opinion only.
