According to the DME rep I talked to several months ago, no, there shouldn't be an issue. I did have a huge issue with Disney's CRO though. They just couldn't seem to get our info straight. But, that could have been because we are arriving on two different days. But, again..DME says it isn't a problem. I would suggest you make your reservations, then when you are closer to your time of travel, double check with DME directly to be sure they have the correct info.
