I have never stayed in Formosa Gardesn but looked at homes to purchase when we were down there. We now own close by in Emerald Island Resort.
You are going to love FG. The homes are beautiful. There is so much in the area for dining and a grocery store at the top of the street. On the corner of Formosa Gardens BLVD and 192 west is a Win DIxie grocery store, taco bell. outback steak house, carrabbas ilalian, giordanos pizza, TGI Fridays, cracker barrel, a doc in a box walk in medical facility, dairy queen, there is the chinese but I would not advise. On the oppisite corner is a red lobster my dbil raved about. Going across 192 from redlobster is a walgreens drug store. On 192 there are countless choices for your group to choose from.
To get to the parks you will leave FG and take a right onto FG BLVD. At light take a right but get into the far left lane because you need to take your first left at the light. It comes up quick if you are not used to the route. That left is sherberth rd and you will follow that down until you reach a light. At that light you are now going to start reading signs as to what park you are going to travel to. You will be taking a left unless you plan on going to AKL to have a look see. I recomend it and dinner if you have the opportunity to do so. It is beautiful.
Have a wonderful vacation.
