Staying at the Flamingo: Will be arriving before check-in. I know I can leave my bags with the bellman, but the pool requires a key card. So the question is, how can I use the pool before check-in? Anyone have experience with this at a hotel that required you to be a guest for free pool usage? It might be worth noting - for those that want to give speculative answers (which I'm ok with) - that the pool isn't run by the hotel. Thanks!
