Couple in late 20’s looking for similar vacation to Atlantis Bahamas. Like the day activities; beach, water park and aquarium and night time at the casino. Don’t like the idea of spending over 500 bucks on a sucky hotel room and no free drinks at the casino. Everything is overpriced at the resort.

Any suggestions for a similar vacation accommodating our likes in activities. I think for 500 dollars I should a decent hotel room at the very least.
Thanks in advance!
