We just got back last night, and we used ME both to and from MCO.
Our experience upon arrival was great - we hadn't received our luggage tags, but we had no problems. Our flight arrived an hour and a half late, but we were met by CMs that directed us to the check-in area. We landed at 11:40 AM and we were in our room at POP at 1:00 PM. We left for Chef Mickey's at 5:00 PM and our luggage was in our room when we got back at around 9:00 PM. No problems there.
Unfortunately, the return experience wasn't quite as good. We received our ME package on our door Thursday morning for our return on Saturday. It said that we should be out front, with our luggage, for a 3:10 PM departure. We called luggage service Friday night and asked them to pick up our luggage in the morning, as we would be in the parks very early. We went to AK, came back, and spent the rest of the afternoon by the pool.
We retrieved our luggage from luggage services, and went out front to wait for the bus. So far, so good. But confusion reigned from that point. A bus was there, but there was seemingly no organization as to who would get on. Then, I realized that there was a CM there that was calling out numbers. I asked her what we needed to do and she said "Do you have a number? You have to have a number to get on the bus". I told her no, that I didn't realize I had to have a number, since nothing about numbers was mentioned in the instructions I had received on Thursday. She replied that "...it's a system I just put in place this morning". OK, then please give me a number and I'll be glad to wait my turn. She didn't know how many numbers she had given out, didn't know how many people still needed to get on the bus, etc. In short, it was a mess. We did get on the next bus, and everything was fine from that point forward, but they could really use some organization for pick-up. Apparently they are having problems with people showing up hours early for pick-up, hoping to get an earlier flight, then there isn't room for the people that are there at the assigned times.
