I Have Some Decisions To Make

In less than a month, I'll be heading to Disney World. I've been listening to Disney World music and whipping myself into a fever pitch of excitement because DISNEY! Music! Food! Dancing! Awesomeness!
I got my travel documents sometime last week. You know once those show up that it's not much longer!
As usual, I felt like I had plenty of time to plan things and well, time is running away from me. Like time does. I mean, the last time I posted here was in March, and I still owe you trip reports. Oops. I have some choices to make. 
In the past, I've taken the Magical Express. It's easy, it's free, and they play the video to get you all excited. My mom and Falandos have never been to Disney World, and I'd love for them to experience the fun of the Magical Express.
BUT. I've been toying with the idea of getting a car service instead.  I've seen reviews for two particular services and ooohhh, it's so tempting. It would be an additional cost for sure, but we'd get a 30 minute grocery stop, where I can pick up a case of bottled water and some pineapple juice for my mom, and we'd possibly get to our hotel sooner. And on our last day, we'd probably get at least 30–45 extra minutes in the parks, so we could leave at 430 instead of 330 or something like that. THAT is really appealing to me, as I do not want to miss the Jammin' Jungle Parade!
So, I did some pricing and looking at the different options. Honestly, I think the Escalade would be the best for us because it would fit all of our stuff (none of us are light packers--Falandos has already prepaid for two carry-ons!) and would be fun to ride around in that. But I'm not one of those people who is obsessed with SUVs--in fact, I strongly prefer to AVOID them. I feel like most people who drive them are bullies and they take up too many parking spaces. And they're ALWAYS parking in the compact car spaces--what is up with that? ANYWAY. I have reservations about that. I was thinking of a limo. Aidan's never been in a limo and I know he'd get a kick out of it. I've been in loads of limos--for all sorts of things. Bachelorette parties, funerals, casino nights, grocery store runs.... so it's not a big deal for me to ride in one. In addition, there was that terrible limo fire that just happened in San Francisco, so I have a friend who is begging me not to get a limo for that reason. A town car just seems boring. I mean, they're NICE and everything... but it's really just a fancy car. 
I would love a car just to go back to the airport... but none of them seem to do that. It's either round trip or one way from MCO to Disney.
The other choice I'm trying to make is whether or not to do the Photopass thing. I want to pre-pay because you save $50 by paying before vacation.... but I also remember feeling so liberated, not having to stop at every Photopass photographer so I got my money's worth. 
So, these are the agonizing decisions that have been plaguing me the past couple days. If any of you have any insight, please let me know. I could use some advice! :)
