I sometimes wish the cruise lines would simply not do them and just tell people upfront - you sail in what you picked.
It may not be the Cruise Line. the first TA we talked to in Oahurst tried to get us to book a guaranty. She told us that we would be upgraded because her office has some much clout. We never booked with her, we chose a different TA because we thought they were pretty straight shooting. I think they have been.
An online service told the same thing to my wife on our first cruise..plus tips were included. Some TA's and places are just not honest. It causes trouble for eveyone.
Maybe there should be a list on Cruise Chat for the top 10 questions and answers. I thik most of us could guess the top 10 questions. Upgrades and booze would be at the top.
