Can you use the resort amenities (i.e. pools, beach access) if you are attending a seminar there but not staying at the hotel?

No one checks. Why not

The beach but not the pools.

I think you can

I think so, there is nobody checking but now I remembered that O had a wrist band. In any case the access to the is free snd you cam take a shower eadily when you come off the beach

They give you a wristband at check in to use the resort amenities. You would need to have a wristband so you did not get kicked out.

Probably lol
