We stayed at Gran Sirenis with out two boys and we really did not like the bathroom being wide open. We did our dressing for dinner etc in shift's.
Large property, but really nothing stand's out in my mind.
Try the H10 Ocean Coral and Turquesa, we loved it and so did most people we have suggested it to.
Upgrade to Preferred if it's high season or if you just want to, great resort and I think one of the best VIP/Preferred Option up or down the Coast.
