I will be watching this thread.
I am trying to plan a FL (non-Disney

trip also in April). Right now we are planning to do 3-4 days in St. Augustine (including beach), 3-4 days at Discovery Cove/Sea World/Aquatica (something we've never done) and then a week on the Gulf Coast (visiting family, Busch Gardens, beaches).
We were looking into Siesta Key, but I'm not sure if it's worth the price for 2 nights. We may just do a day trip to see the beach since my brother only lives a little over an hour away.
I have been going crazy and wasting way too much time looking at Condo/House rentals in both areas (St. Augustine & gulf coast/Tampa area) and if you're staying for a week you can get something nice that is also budget friendly. Our issue is that most places don't rent for anything less than a week during that time of year and those that do have a significantly higher price per night. (3-4 nights costs about the same as a full week)
