yup, studios don't have them, just 1 & 2 BR suites. As far as the non-villas go, some of the high-end suites might have them, but not the standard rooms regardless of location or view.
Do any standard rooms in deluxe resorts have whirlpools? I don't think so but I could be wrong.
As a DVC Member who's stayed in a variety of the resorts and rooms, I can say the only rooms I've ever had a whirlpool in were DVC 1 Bedroom and bigger. So, I logged into our DVC Member site and pulled the following up for you, hope it helps (Look for the Smileys below):
