Dhill, the people here are friendly but we don't always know the answers.
I did sail the itinerary that you are doing, but I did that on the Infinity a few years ago.
Back then they did have all night tenders, but things seem to change so I did not want to give the wrong info.
I will tell that that was a wonderful cruise for us.
