We have about 5 months to go BUT that doesn't stop me from planning ahead. Checking which eateries will be open, which rides will be refurbed, what special events we want to plan to attend.
THEN about 3 weeks before, I start checking accuweather.com b/c they have a 21 day weather forecast. That's when I start planning our packing lists for myself and child. 2 weeks before I update the weather and change this lists. I start pulling out different things that we will need and stocking up on travel suppiles. 1 week before I finalized the packing lists. At work I start planning for my sub since I'll miss 2 days of work. The day before we leave, AAAAAHHHHHHH!!!!! I am giddy! You can't wipe the smile off my face. So WORK??? Hahaha, Funny!
