We have never been to Cancun or any part of Mexico before, so not sure what to expect. Four of us: me, wife, 3-year old, and an infant. Hyatt Diamond status, so that is why I am looking at the Hyatt hotels. With a baby, we are probably limited to the hotel area and nearby vicinity. We are looking for some nice beach and warm weather for this January trip of about 1 week. Direct flight from PHL preferred.

Some thoughts:

Hyatt Aruba - no diamond suite upgrades available. A little far ...4.5 hours by plane. Heard good things about Aruba and its safety.

Hyatt Ziva Cancun - got good reviews here, but not available on points. I might have to use my Citi Prestige 4th night free, but still expensive.

EDIT: I also have lots of IHG points. So, wondering if Intercontinental at Cozumel might be a good choice as well.

Grand Hyatt Playa Del Carmen - Is there anything to do nearby? How's this hotel for kids over Hyatt Ziva Cancun?
