I guess I've never payed attention before. How long would you say it takes you from MCO to the parks?
We arrive at MCO at 9am, MExpress to All-Stars. We'll have checked in online, so we'll show our faces at the desk, check Magic Bands, and head to the MK. I was thinking by noon. Is that reasonable?

Once the bus gets going, it takes about 30-40 min to get to the resorts, depending on which one you are headed to. I know the Colonel has said that the ME buses wait for 30 min and then they leave, so you should be at your resort in max 90 min. Have fun!
We plan on 3 hrs and we've done well thus far.
Hmm. We landed at 9:15AM, took DME, checked in, and were in AK by 11:30!
Thank you! Glad it seems like it will work. I like nice round numbers, so I decided we need to be in the park before 12, or risk a crying tantrum. And I'd be the one throwing the tantrum!
