I will be staying at ASMu and want to do online check in from the hotel for my flight home. Is there somewhere I can use a computer or plug a phone or tablet in to print my boarding passes?
I'm not sure how or why but our boarding passes were hanging on our door the morning of our departure. Magic Express notice was delivered the day before. We did online check-in 24 hours before our flight (Southwest) and were prepared to ask them at the airline check in desk to print them the next morning when we delivered our luggage for storage. (It's located on the bus stop side of the resort on your left as you exit the Main Building. If I remember correctly, they're open from 5 or 6 AM until Noon.) Your best bet will be to ask at the front desk and they'll be more than happy to answer your question.
Yes, there is a printer that can be used. My son had signed his kids up for the kids' marathon events and his printer died before they left home so he didn't have the confirmation sheets that were needed to check in. All he had to do was log onto this email account and he was able to print the necessary stuff.
Not certain about Values like ASM, but at POR, they were able to print out our passes and check our luggage prior to boarding the Magical Express on our departure day.
If using Resort Airline Check-In,you will get Boarding Passes on your door(if for some reason they don't make it to your door,RACI can print them when you take your luggage to them).
For Southwest,I usually get a "mid" B seat from RACI.
Not sure if you have considered it, but I would recommend your airline smartphone app. You can check in and have your boarding pass on your phone. Just make sure it is charged
