Codeshare flights and Magical Express

[Howellsy]

We're leaving a week today!

But onto my actual question we're flying with Virgin but we booked with Continental - when I booked ME I gave them Continental's flight number, but I'm wondering now whether that's ok? Should I call and give them the Virgin flight number instead? I'm guessing that as long as they know the time you're scheduled to land it should be ok anyway, but I just wanted to check

Alsoo, I used the WDW US online check-in service - has anyone else used this? Can I still ring up and request a room or will I already have been assigned?

Thanks in advance for any help!!
