You're going to love it. Here are some suggestions:
-I highly recommend "splurging" a little and try Palo (brunch or dinner) and Remy (dinner). Both are so romantic...!
-I'm not the biggest fan of bars but Pink, Skyline and 687 are great.
-If you like alcohol, I also recommend the Wine Tasting class (At Pink) and the Mixology class (At Skyline). There's a fee for it (usually between 20 and 35$) and trust me, you'll get out of there tipsy! The wine one is very interesting. The Mixology one is super fun!
-Cove cafe has a fee but they have excellent choices.
-Senses Spa is great. We have tried the Rainforest day pass. It a good value for the price.
-The Quiet Cove section is very nice. The pool over there can be crowded but I've never seen it become a "human soup" like the children's pools.
