This happened to me too !!! (i.e. the wrong resort info) - when I called MS - they told me that if I decided to use the yellow tags for luggage delivery, to just cross out the wrong resort and write the correct one in (i didn't like this and thought that they should have offered to mail correct tags - but since I'd rather pick up my own luggage and transport it on my own to prevent any unfortunate mishaps - it really didn't matter)...as for the voucher - they told me they made a note of it in the system and that I should not have any problems when checking in with ME...but I am going to call again before I leave to make sure the right info is in the system...
