We always do online check-in. The check-in lines can be long at times, so we've found it to be a time saver. During our July trip, we stayed at POR. The check-in line was huge when we arrived. There's a separate line for online check-ins. There was one party being helped at the online counter, but there appeared to be some complication, so a CM took us over to a Concierge CM right away and had him check us in. They don't just hand you your room key and off you go. They take the time to verify all the members of your party, double-check the credit card on file, explain the resort, and show your room location on the map. It's the same level of service you'll get at the regular line without the wait. The whole process took less than 5 minutes. By the time we were on our way to our room the regular line was longer than ever and didn't appear to be moving very quickly.
