Donna hoteru ga imasu ka?
She'd most likely give a description of the hotel, since 'donna' means 'which kind'. If you wanted the name of the hotel, you should use 'dono'.
However, in spoken language, 'donna' is more often replaced with 'dou iu', which means exactly the same thing but is slightly easier to pronounce.
Also, the rest of the ko-so-a(-do) family have counterparts 'konna', 'sonna', 'anna', which similarly can be replaced with 'kou iu', 'sou iu', and 'aa iu'.
kou iu kurama ga ii n da yo - this sort of car is good!
sou iu hito wa baka da zo - those sort of people are idiots!
aa iu tokoro ni ikitai n da na - I want to go to that (faraway) kind of place!
I've never actually heard 'aa iu' though. There are various other uses of these, but if you're a beginner I wouldn't worry about them yet.
