I reserved rooms at both for 3 nights in Feb. Cost is very similar. Not sure if it will biased because this is the Hyatt sub-forum but what do you guys think?

Hyatt Regency Waikiki
$856.80 including parking and resort fee using a diamond suite upgrade to ocean front suite with regency club access

Sheraton Waikiki
$903.54 including parking and resort fee (platinum status, suite upgrade requested) AAA Breakfast Rate
