Great idea for a post. We (me and DBF) are going on Jan 22nd. It's our anniversary that day. We have CRT booked the evening before for the 'formal' celebration, but decided to do this as our 'silly' celebration. No kids but figured we'd still have fun.
Might be worth noting r/e tickets: I originally ordered my tickets around July 7th and was assured I would receive the tickets within 14 days. One month later I was still waiting so I call WDW and they agreed to re send them. This time they send them by DHL (I love in England) so they got to me no probs. So if you think your tickets got lost in the post, just call them to sort it out.
As we don't have kids, we won't have full costumes. Whilst at DLP last month I bought DBF a Pirate hat and eye patch, and myself a Princess Crown!
