There are a TON of activities at the Hyatt Regency resort - if you are staying there, you really don't need to leave!
However, if you are looking to explore the area, there are also so many fun things to do and places to eat/drink - here are just a few family classics:
If you are staying at the Hyatt Place, walk outside and you'll find the outdoor mall. It is down the road from the main hotel. They have everything!
Pinchers
28580 Bonita Crossings Boulevard, Bonita Springs, FL 34135
Classic spot as they have seafood and 2 for 1 drinks all day every day!
The Fish House Restaurant
4685 Bonita Beach Road Southwest, Bonita Springs, FL 34134
Good food down the street from the beach!
Doc's Beach House
27908 Hickory Boulevard, Bonita Springs, FL 34134, (239) 992-6444
If you make your way to the beach, be sure to stop by Doc's Beach House. It is a classic Han/Latham stop for a pitcher of beer on the beach (warning, they are cash only). There are also water rentals right there if you want to jet ski/parasail
