I get it all the time. We start out counting around 200 days out, I plot and plan and read and seek everything Disney, been there over 38 times, list pack, pack 2 weeks before actually leaving and at about 2 days out start the doubt process. Should we stay home, work on the house, spend the money on repairs, long trip, security in travel etc. But once I board the train, we use Amtrak, sit back and put up my legs and grab my play sack, Gameboy DS, crosswords puzzle books, novels and portable DVD player, I'm in the mood for a vacation. The train lulls me into relaxation, peace of mind knowing whats on the other end. Too much antipication builds when we detrain in Kissimmee and cab over to WDW, first spying the monorail tracks to pulling into our home for 10 nights, either the Poly or WL, and after the check in process, voila! I'm home, relaxed and giddy as a little kid and we're in our late 50's. Change into our suits and jump in the pool, have a drink or 2 and, man this is living. If God made anything better he kept it for himself!
Going home is awhole nother problem and rather not discuss it!
