We recently did a split stay. 3 days at Caribbean Beach and 7 nights at Beach Club Villas. ME was very confused by this scenario. I got tags and vouchers for going down to Disney and had return vouchers for after the 3 days. I called and explained this and was told
DVC resorts scheduled their own ME. SO I called MS and explained we needed a voucher for leaving BCV.
Got those too. ..........
We got an earlier flight...called from the departing airport to inform them that our flight iformation had changed..No problem.. .. We then arrived in Orlando and headed down to the line to get check in to ME. This guy printed out a whole new slew of vouchers because he said they were messed up.....
We had a great vacation.....
The night before you depart you are supposed to get an ME departure time under the door. It's usually about 3 hours before your flight... Nope we didn't get one at the BCV... I went down to Bell services and they sent me out to the valet.. He asked what time my flight was and he wrote out a voucher for my family of 5 and said return at 2:40 to board the ME...all he asked for was my departing flight time.
We walked over to Epcot for a few hours and came back....THe bus driver asked for our vouchers and I handed him a stack of vouchers and said use whatever ones you want just get me to the aiprort.
Long story short... If you have your arrival tickets then you are set. ...if you call you'll just confuse them and end up with 8 sets of vouchers.. I would make sure to check in with the valet guy when you arrive. It is really nothing to worry about.
Have fun.
