Thanks for your comments. I did look to see if the cruise was available in 2025, but it isn't. However, financial constraints mean that 2026 is better as it's longer for us to save!
Decided to take the more pragmatic approach and do nothing until nearer the time, after all the price may drop!!
With family living abroad with our first grandchild, visits to them will almost certainly take priority in the future.
In the meantime we look forward to our cruise on Queen Anne in August.
