Have you booked it yet? If not, you might want to do it pretty soon so they have time to get your stuff out to you. And you could check over on the Transportation board for more info. But, in the meantime, I'll tell you how it went for us last month.
Arrived in MCO at about 11:50 on Sat 6/18. (flew Song out of Boston). We found the check-in desk and were on a bus by 12:15. Left MCO at 12:30ish. Stopped at CBR first, then YC, and then BC...our resort. Our check-in process went quite quickly. My dh left from BCV about 4 days later. He never got any DME info under the door the night before he left. And since I'm basically an idiot, I forgot to give him the voucher for departure from our packet. But he got on an 8:30 bus, for his 11:45 flight.
We moved from BCV to POR on 6/24. Again, no departure info the night before we left from POR (6:26) And again, I forgot about those packet departure vouchers. Bell Services at POR gave me one, since mine had gone on ahead to the airport. But I digress....at 8:40 I called Bell Services to have them get my stuff to the ME desk. By 8:50 I was at the desk, getting my boarding passes for dd and myself. They weren't too sure which bus I should take to the airport..the noon or the 12:30. We showed up again around 11ish and the crowd at the desk line was huge...but there was a large group leaving, so that might have made the line longer than what would be normal. Since I already had my boarding passes, I just had BS get me that voucher. The line for the bus had already gotten long (again...that large group...a convention type thing for Pampered Chef). So, we got in that line. Driver told those traveling without luggage to come to the front and board the bus. That would be us!!! Only had carry-on since we were flying Song, a participating airline. Hopped on the bus at 11:50ish, the bus finally loaded those with bags to store under the bus. We left at 12:10. Made no other stops since POR people had filled the bus!! It was wonderful to get off that bus and just head right to security. We got to our gate at about 12:45...for a 3:00 flight.
I'll be using DME again in Nov and again in Oct '06!!!
