Glad you've got the important things done

.
Have you made plans for your FPs yet? That will be the next thing - if onsite, a bit longer to wait if not.
Who have you booked for transport? We fly into Sanford too and I haven't sorted this yet - keep putting it off tbh. We are off to Universal first so it's a fairly hefty price for the cab, but I can't see the point of paying for a hire car to sit in a car park for 3 days and pay parking on top. We are only hiring a car for 4 days mid trip to do shopping/DC. My parents are doing KSC but are getting transport included

.
I presume you are flying on the Dreamliner - I have heard so many mixed reviews about it. Mostly good, but some not so

. I *think* when we went to the Red Sea with Thomson a while back, we checked in 2 weeks before as well.
Are you going for 2 weeks? I ask because I can forsee an issue with booking our flight seats as we are going for 3! Which means most of the plane will have probably already booked by the time we get to! The 90 day return thing is ridiculous - why they can't do it from 90 day outbound I'll never know!
Re travel money - it's dire atm. Have a look at moneysavingexpert for the best deals around. Failing that, I always seem to find that our little local independent travel agents has one of the best, if not the best rate around. I guess they try and add a bit to get the business. I checked yesterday and my local was offering 1.489 which is among the best about atm.
