Standard upgrade is to Park Suite which is a Junior Full Suite (no separating door, but and full living area with additional half bathroom). No masking even from staff. Quality of service varies. I found the FOM and the Associate who brought us to the room to be exceptional. F&B staff at Dining Room was a bit mixed. Didn’t interact much with anyone else. The one new development I saw was the Dining Club program which is interesting, particular for non-Globalists.
Yes, used points. I was very impressed by the hotel but Stone Town itself is a 1-2 day site. Globalist breakfast was great, enjoyed very much. They do rotate some of the hot mains out daily, but a majority is kept. I really enjoyed the bottled juices (Pomegranate, hibiscus, and watermelon). Opens at 6:30am but seem to be fully set up at 7:30am. Very much island time in Zanzibar. They also had coconuts on demand which is a concept that is new to me.

Coconuts on demand

Sorry SanDiego1K I missed your last question. I had 4 nights/3 full days in Zanzibar and stayed entirely at the Park Hyatt. First full day I was sick so stayed in. Second day explored Stone Town and Prison Island, highly recommend snorkeling at the latter. They have tons of tortoises from Seychelles, but there’s no barrier like in La Digue. Third day hired a car and a driver and explored the island. Jozani Forrest, Rock restaurant, Michamvi, Kuza Cave, Mtoni Palace Ruins, Baraka Natural Aquarium, and Nungwi were the places I recall. Lots of police checkpoints so wouldn’t recommend self-driving.
