Hi Sue yes I'm going on this trip but it's not my first time, I think I'm into double figures of Just You holidays now! Sounds like this will be a great one. I see you asked about visas - it looks like you can apply online up to 3 days before travel but if I were you I would keep an eye on the government site as all changes are made there, just type FCO into Google and you will get the uk government foreign and commonwealth office which has so much info on lots of things other than visas.
Look forward to meeting you on the holiday.
