Problems with back to back cruises.

It's true what they say you know. You're never too old to learn something new.
At least that's the conclusion I've come to this morning after speaking to a client and then the cruise line about booking a back to back cruise for him.
I'm posting what I found out here for you as it's possible it could ruin your holiday; so if you're planning a back to back cruise it's worth double checking with your travel agent/cruise line.
