I spoke with a CM at the ME center. She said that as long as you have a reservation with ME, someone will be there. Our flight is supposed to arrive at 10:23pm, but it never seems to go that smoothly for us. She said that they keep track of flight numbers so they know if your flight will be late. I was also told that there would not only be someone at the welcome center, but a CM with a sign still working too, no matter what time...again, as long as they know you are coming. How many times will I call to check???
She did recommend that we get our own luggage as it would be delivered in the middle of the night if we sent it with the ME people. I would have done that anyway, don't like to leave things to chance!
No reason to get a hotel near the airport. The number for ME is 866-599-0951. If you talk to them and get different information, please post!!
