Then specialty restaurants a good option. If you don't want unlimited SP restaurants, try to join them in blu. Not as good as costal kitchen, but you can dine together free. Also, I once changed my stateroom when I boarded to a suite.
A couple didn't show up and I was moved when the cruise was leaving the port- the cost was actually less then the move up program minimum. So try that. Also lot's to do for the older generation and those in-between. Enjoy
