No, there are no room blocks. However, there are a ton of hotels to choose from in downtown Sarasota. We recommend The Westin Sarasota, Ritz Carlton, and Art Ovation Hotel.
Yes, there will be street parking at The Hepp Residence, but feel free to Uber and/or carpool if you don’t want to worry about finding parking. The hotels are within a few miles of the wedding location.
