I'd do exactly the same thing again and indeed got a slap on the day for saying "I think this is exactly how I'll do my next wedding" :)
Seriously though, despite hating our disney wedding coordinator, she was rubbish, it all went perfectly and was beautiful from start to finish. Even the limo ride around celebration and the "snow". Perfect.
It was expensive but worth it.
Now the hairdressing. At the time we got married Disney did all that as part of the package. The Disney folks came to our room, threw me out :/ and worked their magic. I believe that you now have to make your own arrangements with a local hair/makeup place of your choosing.
