Does anyone know if Fishbones has outdoor dining? Have been there only one time and can't remember.
Lake Mary is a bedroom/business community that up until 30 years ago was mostly orange groves. So, we don't have a heck of a lot of touristy type stuff. But, here are a couple of ideas...
Downtown Sanford has a number of nice shops (mostly antiques) and interesting restaurants. It's got kind of a rescued from the 40s feel to it. The shops don't look like they changed much, but they did a street-scape project so the road is cobblestone and pretty nice.
Sanford itself actually a port city (at least it was decades ago) and right on Lake Monroe, which leads into the St. John's river. I nosed around in Google and saw that they've got an airboat ride that goes out of downtown Sanford, but I don't really know anything about it.
There's also a lunch and dinner cruise that goes out of Sanford. But, I checked the schedule and for whatever reason it doesn't seem to go out on Friday, which is odd. If you're interested in something like this you might give them a call.
Lake Mary itself has the Seminole Wekiva Trail, which is a paved sports trail that goes several miles in each direction and has some very nice sections (none are really bad, just boring). It's good for a nice walk, and better if you can find bicycles. You should be able to ask the folks where you're staying which direction is best for you to head in.
What we do have is a decent selection of nice restaurants. We usually head over to Colonial Town Park ourselves. There's also a very nice Panera Bread in Heathrow, and a Stonewood steakhouse. And, Lake Mary has built a little down-town area over off of Lake Mary Boulevard. I've driven through there a bunch and it looks interesting, but I've never actually eaten at any of the restaurants.
I hope this helps. Let me know if you have any more questions.
