As our daughter is currently rearranging her long-booked wedding from this August to next year I can fully understand the summer availability issues. :-(

Well done for persevering with this, late April is a good fall-back option with longish days and often good weather; lets hope most can make it and the hotel is fair to those who can't. +++

In all fairness, I think the organising group have done a magnificent job to date, and what David has posted seems from my perspective to be the best solution from all sides. Now we have something to look forward to.

+1 from me
PS. don't forget Jordan, he is missing the Annual.
April '21 is good for us both.
