So, I am finally managing to get the time to update on how things went.
Firstly, thank you to everyone that commented on how to do things etc as they really did help (usually its the DW that sorted this kind of thing out but obviously she couldn't support this time

).
The reveal was fantastic. I went with the 'fake' reveal using the pieces of paper first that spelt out that we were in the 'US' and that we were going to 'NASA' (put together and they spelt NASSAU)
Then came the real reveal. I had been giving her a Mickey shaped tab that had a number/letter on the reverse every week for 50 weeks that, once put in order, revealed that we were all going on the Disney Wish the following morning - tears flowed, disbelief ensued. All was done down at Disney Springs, which was extra special as the visitor centre has got a scale model of the Wish - I was able to point out exactly which cabin we were staying in !!!!

One funny story, though. The night before I did the reveal, we got chatting to a lovely lady sitting on a bench at MK. She told us that she had flown down from Boston to surprise her grandchildren, which I naturally thought she meant in MK. When I asked her this, she replied, 'Oh, no....we've (her and her DS) booked a surprise cruise, on the Disney Wish sailing on Friday 22nd (August)'. I couldn't believe what this random lady, on a random bench, in MK, had just said

My DW, DD, and DS all knew I'd got a surprise lined up for Friday 22nd but luckily, I'd lied about its duration by saying we were away for just one night (phew). Disaster averted

So, Donna from Boston, if you're in these boards, thank you for the heart attack

but also thank you for the added memory for our
Disney cruise
