No one going at the same time you are, we have had the same response for when we go on the 25th June (same ship) still it's a long shot.
Hope you have fun xxx
We went on 22nd January this year, there was no response to our post either. Don't think many swingers do cruising - maybe one of the naturists cruises would be more beneficial for that! Have a great time, it's a fantastic ship - we've been on it twice now x
