Because you have little ones, you only need one room. Ask agent for the upgrade to ocean view. Recommend you ck for rooms overlooking the pool, near the tower--some are off to the side. It's a small place--with shuttle to rooms--almost everything is UPHILL!
The iguanas are all over the place, food is nice--make sure the adults get a night alone (with sitter) to eat at Italian or get the fried chicken for the kids--it's more than enough for 3-4 little ones and just excellent!
We took the $5 boat ride to see dolphins--they were all over. We took free walk w/guide thru "jungle" canopy right at resort---monkeys!! We also did the WitchesRock zipline (no little kids--but our youngest was so small he had to be taken on the lines--not enough weight! Don't miss that if you and the mrs like a bit of adventure. Rent a car, but get your insurance coverage thru credit card company like amex--they sell policy for $25 for the entire rental--otherwise, rental car agencies will hit you with the mandatory rates they offer. Do your research andget a good deal with the details in writing. We had a manual and it was really cheap, even if it didn't want to go up hills ...without a fight!
