We'd recommend this if you're looking for a calm but fun get-away. They have up to five swimming pools and have rides like the Tornado, Pendulum and a couple water slides. They offer classy rooms and suites, and also a great dining experience, so go here if you want to spend a couple of days out. They have packages for parties, and functions and do take online reservations.
Price: INR 400 - 500. No stag entry allowed
Must Try Ride: Pendulum
