Sounds like you received a similar MoveUp offer to the one we did for our March sailing. Compared to the offer minimum bids, the Aqua Sky Suite was the least amount from our initially chosen Aqua cabin. We decided not to bother as I thought the amount, once doubled as it’s pp, was better spent on our ports instead. We had Blu and it meant we’d really be paying for a slightly larger room; every time we went past the Retreat Lounge, Michael’s Club, it was empty, so I don’t think that would have interested us either. Additionally, you don’t get the upgrading CC points. Obviously, it’s personal choice but we decided against it. In fact, we’ve used the money for an extra cruise later this year 😉.
