FWIW, we booked 2 VGT cabins for our Norway cruise in Sept 2019. Our kids were 22 & 19 at the time and we could have booked them in their own cabin but our TA suggested to book with dh in one cabin, and me in the other, and it would increase the odds that our rooms connect. We had a great location, deck 6 midship, and could open the balcony divider to create one huge balcony. It was really nice.
We are booked for a 4-nt in September, our PIF date is not until July, and already they released VGT rates that are much cheaper than our OBB discount. We have a great aft cabin reserved, but the $600 savings is tempting. I think I'd rather book closer to the sail date if I need to accept the limitations of a VGT though.
DCL website should make it abundantly clear that the non-refundable policy of VGT/OGT/IGT does not override the 14-day cancellation for covid policy. People ask this so often (rightly, they should) and I'd guess DCL gets plenty of phone calls asking this same question. Maybe if their website gave a better explanation, fewer people would need to call in for simple questions, and it could reduce the crazy long hold times people are experiencing on the phone.
