I will be traveling on the Fantasy in March with 3 boys - ages 5, 10, 12. I thought I would put them all in Oceaneer Club together, but it looks like the Edge would be a better fit for the 2 older boys. Is there any flexibility in getting my 10 year old in the Edge with his brother? I thought I read that whichever club you sign up for, you are committed to that club for the entire cruise. Is that truly the case, or can my 12 year old go back and forth between the 2 clubs? Thanks for any advice.
