Best Wishes on your upcoming wedding!
My personal favorite is Siesta Key public beach within the city limits of Sarasota. The sand is as white and fine as sugar. Lido Key, also within Sarasota, is nice, too. You may also want to visit Longboat Key and Anna Maria Island.
And we get beautiful sunsets here on the west coast of Florida. You can have the ceremony on the beach and also the reception. There are many excellent caterers listed on www.ElegantSarasotaWeddings.com. If a beach reception isn’t what you have in mind, check out the Reception Locations listed there.
You may want to wait until May, when room rates go down at most motels. And you can probably get better rates if you book a block of rooms.
All the best,
