1. You can go to the purser's desk at the start of the cruise and ask for the automatic tipping to be removed from your account (you will find various views on the merits or otherwise of up front tipping on this forum). 2. If you book and pay for a balcony cabin, that is what you will get. If you don't, I would imagine the chances of being upgraded to a balcony cabin are very slight. 3. If you choose Anytime dining, you can dine with different people each night if you wish, or you can book a table for two during the day if you prefer to be on your own.
