Are you able to use the Hyatt hotel amenities if staying at residence club?

I spoke to them today; you can use the hyatt regency pools but not the fitness classes/kids' events at this time.

Yes, the Hyatt Regency right next door has beautiful pools and fantastic slide which you are allowed to use.

According to the front desk, guests have access to the pools and fitness classes with no additional fee. Guests of the Residence Club are not permitted to use the gym or the Regency Club.

Yes you can use all the amenities at the Hyatt Regency including their beautiful pools.
