After I won my cruise with them I emailed them and asked if I could get another cabin for the same price and they responded with a yes, so our friends will be joining us. On the hidden charges - it tells you exactly how much more at the bottom of each cruise auction and how much more for certain dates, also they have a 15.00 booking charge. They only charged us one time for both cabins. They give you an 800 number you can call with any questions. So far they have been great. We can't wait.
