there are fans of grand hyatt tokyo club, top suite there has a swimming pool
(dont think any hyatt regency have top suites like some (not all) grand hyatt..)

rio (suites)
berlin (club)
multiple asia including bangkok (spa cottages)

like every other brand (including all but one of the most expensive and luxurious brands) there is extremely dramatic variation within brand portfolio
