I got back the final quote....
$396.00 plus tip from MCO to port (this includes a luggage van)
$453.00 plus tip from typical WDW resort.
They have 2 hummers in their fleet. I can reserve them now. Since there seems to be a large interest in getting to the port this way, please PM if you are interested, from where and how many in your party. Let's see what the numbers look like and we can go from there...
From the posts, and I realize none of this is set in stone....it looks like these are the ones who might be interested....and if I missed you, I am sorry

it is hard to catch everything in all these posts, but please PM me
Of course the question for some of you traveling without kids...would you mind kids in the Hummer with you or do we want to try and split into family one and adult one?
If there are enough people that def. want in, I have no problem reserving it now. It takes a cc number to hold the reservation, but you can cancel up to 1 week before. I would think if we set up a 9 or 10 am departure from MCO that would allow most red eyes to arrive and those sleeping there to get up and still get us to the port early.
Thoughts?
