Cosmopolitan Vegas corner balcony was pretty nice. I bet that balcony was 100' long total. Room was massive. We used it as a meeting point for the group of 12 before going out and everyone had space to spread out and chit chat.
Marriott marquis Miami was a huge room. Like just the bedroom and bathroom were bigger than typical suite. Then it had a whole living room, kitchenette, second half bath. Main bath had a tv screen integrated into the mirror.
We had the eagles nest at the springs arenal in Costa Rica. Not a hotel room per se, as it was 3 kings and 1 queen and 4 full beds in total, with 3-4 bathrooms and a full kitchen/ living room. Private hot tub.
