I used online check in twice this week, once for CBR and once for OKW. It was great. My request which we made at originally was in there and was granted.
I will use it again. It really shortened check in time.
Right now there doesn't seem to be a lot of people using it so my line was nonexistant.
However if someone wants something changed with their reservation it is going to take them longer at the counter. If everything is just right, then your check in is very speedy.
The CM offered to move us from Millers Rd where our assigned room is to Turtle Pond, which I could have done (we usually stay at Turtle Pond) but I decided to try a different side of the resort this time.
Have a good vacation!
