shburks, we've done one-way ME many many times before, including ME from BC to the airport following our
Disney cruise. We've also done one-way ME from WL to airport, AKL to airport, CR to airport and YC to airport.
We're doing a one-way ME from BWI to airport later this month and as usual, I received an ME booklet with vouchers for BWI to the airport. Our back-to-the-airport vouchers always have "no flight information provided" for the arrival and our flight information for the departure.
So even if you're booking just one-way ME, you should receive the vouchers. If you don't receive them and it's less than 45 days before your trip, I'd call and check the status.
