My husband and I cruised for the first time last year and LOVED IT! Going back again, this time with the kids (19 and 15). We'll be on The Adventure of the Seas in August. I read some old posts about the arcade and I wonder if someone can update me. What is the cost of the games? Does it work strictly off the Sea Pass? Can I set up a limit? I'm sure they'll both be in there constently and I want to prepare myself.
