We stayed there the first time using the Ent. discount over Memorial Day 2 years ago. I think the jr. suite at the Swan (different than the jr. suite at the Dolphin) was only $175, but that was 2 years ago.
Now, their high and low seasons are really different since they are a convention hotel. You can call them and ask for a price with then Ent. discount without having the book or card. I've never had a problem getting a quote without having the book. Give them a call and see what they have to say. You can not beat the location for the price by staying at the Swan or Dolphin.
