Hi PollyA
I have had brunch at a Raddison Hotel several times, but not the one in Orlando. If you are talking about the Sunday Champagne brunch then it is fantastic but not something to be undertaken lightly. Put aside a few hours, make sure that you are hungry as it is all you can eat and drink, then go and enjoy. The variety of food is amazing and there is no hurry to finish. This used to be a "must do" on holiday for us before the children can along.
