I am getting married at The BeachHouse in November! It is very reasonably priced and they don't nickle and dime you for extra costs (i.e. cake cutting, heat lamps, etc).
Contact them on their website and they'll send you pricing.
As for accomodations, we are suggesting Shorewalk Vacation Villas in Bradenton. They are 2 bedroom units (sleep 6) with full kitchen, laundry, livingroom.
Please let me know if you have any questions on The BeachHouse.
