Hi there. We are counting the days until our Grand cruise on 5/20. My TA asked if I wanted an upgrade. We have a great mid-ship location with a balcony. I said no because I saw that most of the suites are up front or in the back of the ship and I worry about the motion. My question is this: can you refuse an upgrade if you are offered it when you check in (and it is not in a good location) or is it too late by then. Just wondering.
