lol @catlover!! We definitely thought the same, the discount on the cruise was worth more than any possible interest!
And as you suspected, our travel agent just let us know that we have been moved to the Antartica xmas cruise on Venture.
No paperwork yet, I imagine Seabourn has their hands full at the moment and we must be low on the list given how far away our sailing is. So still waiting to find out what will happen to the specific room we selected, along with this being the first time we paid in full in this far advance, it's also the first time we selected a room in advance 😛
