Also is DME travel tied to the day of my flight? ( actually I could just leave my original flight info that was for the next day on the original package plan. they don't know I flew in the night before on a different flight? )
.Now I'm thinking of doing this since this time it might save us some money.
We are thinking of flying out on a Wednesday but at an airport a little over an hour away. The flights are $500 cheaper than our closest airport.
We would drive up a day before and do a park/sleep/fly package at a hotel near the airport since we want an early morning flight. The cheapest I could find for a DECENT hotel (that doesn't look disgusting) is $160 for the night which included free parking while away.
I'm thinking of driving up that Tuesday like we planned and doing an afternoon flight. Something around 2-3 pm and getting to Disney a day earlier. I could stay at POP for $90. I could pay the parking fee at the airport or a nearby hotel for about $5 a day. I would still be saving money.
Decisions....decisions...

The first time we moved from Boardwalk to Art of Animation Little Mermaid rooms, cost me $137.00 and we still got magical express. Super easy!
