Hi
Fellow UK bride here - we are getting married at the end of August 2013, so I totally understand everything you are going through - we were meant to be getting married orginally this month 2012, but due to circumstances had to piut it back a year - I have been sooooo impatient!
I'm still waiting for the month date but as everyone else says there is still loads to do. Due to when you are getting married you may get lucky and get free dining. I sent out save the dates in Feb this year - just postcard magnets but with a pre-RSVP so I could get back guest numbers by the end of March 2012. Thats because normally the holidays for the folloing year are out to book in April, so I wanted to be ready as I was praying for free dining - lol!
We go lucky, and free dining was available, so most of the guests and family has all booked Disney. We did this direct as it was cheaper, just went online - so all park tickets, rooms and dining is sorted. From the UK the flights aren't out until at least 12 months before. We should be able to book flights in Sept/ Oct this year - again direct as it's cheaper.
Just hint if you want ideas on prices, go on Disneys website and look at accomodation for this year - prices dont change hugely. Our friends and family are staying at all different Disney places - grooms parents are a Old Key West in a villa, by parents and sibling are in Saratoga in a villa, friends are in Coranado in a room and we are going with Animal Kingdom lodge aswe have stayed there before and LOVE it!
I have my dress, grooms suit - you may want to check out buying in the UK vesus renting (prices are crazy whn you want the suits for 2 weeks or you could even rent in Florida. Bridesmaid dresses are bought, I have a florist sorted in Florida and also have booked the reception venue over there. It tkes time and e-mails, and people thin you are a bit nuts planning so far in advance - like you I couldnt work out why it is so short compared to the UK whih is like years ahead??? Saying that, my friend got married at the Bellagio in Vegas 2 years ago and i was exactly the same thing - and her wedding was AMAZING - I think they just do it better in the States, and so Im not worried!
Hope all goes well and happy planning!!!!
