I really wouldn't worry about it. We just got back today and they didn't even look at our vouchers...for instance, our vouchers had us arriving on 5/20, and departing on 5/14...obviously backwards. No one noticed (other than me), mainly because MOST everyone's voucher booklets are totally wrong. So, your misspelled name will be the least of their worries!! Oh, and don't worry about the missing departure info...despite having mine in the book (albeit wrong), they still hung a note on my resort door asking me to call and confirm our departure time. You'll be fine...have a GREAT trip!!
