Do they have a pool open to the local community? Like a resident member pass or something?

They do have a pool and you can purchase a day pass. I'm not sure what it cost. Call them to verify.

They have pool and other amenities. Though it's only for customers staying in the hotel and not for other local residence.

Yeah but you have to be staying in the hotel to get in

They have a pool, but I don't believe they have anything like you are inquiring about.
