Here's a quick summary based on reading both threads comparing the two:

Hyatt Regency:
Ocean views and location on the beach
Regency Club
Older property, larger with in hotel shopping mall like levels, more dated
Cat 5 compared with Centric Cat 4
WiFi issues

Centric:
Newer, more contemporary vibe
Location not on beach
Rooms are more updated/current
Cat 4
Suite redemption with mountain & city views, some ocean views
Strong WiFi
Breakfast not open during covid, 500 point granted per day, no club
Better workout room

Any other inputs?
