just curious what the benefit is
If you have specific room requests that you really want, I would NOT do online check in.
I had requested high floor and closer to main lobby and food court due to injury and the room assigner put me in the back 40 of the resort which wasn't going to work for me that trip (knee injury) and I ask to have my room moved closer to the main area if possible.
According to the CM that was handing me the check in packet, it was hard to move me since I did online check in. I nicely insisted and it was a pain to get everything changed. It would have been faster to use regular check in.
I no longer use online check in. My last 2 trips (May 2013, Sept. 2013) the lines for online check in were longer than regular so I was glad I hadn't used it.
If you don't do online check in does that mean your room is not assigned until you arrive?
No, all rooms are assigned prior to your arrival.
And the CM that told GaSleepingBeautyFan that it was more difficult to switch rooms because they did online check in was mistaken. The process is exactly the same to get your room switched whether you do online check in or not. Now the CM probably just didn't feel like reprinting the paperwork and KTTWs for the new room. But those would still have to be printed if you didn't do online check in.
I have done online check in 3 times, with room requests on 2. I was upgraded the first 2 times (standard to wood view at WL, standard garden view to deluxe at GF) & received exactly what I requested the 3rd time at WL.And the CM that told GaSleepingBeautyFan that it was more difficult to switch rooms because they did online check in was mistaken.

This will be our first trip to Disney and staying on property. I would assume it would be more benficial to not check in online and have a CM go over everything with us at check in?

Can someone tell me why you have to put a card on file for online check in? Do they place a hold on this? I dont understand why they do this. If you dont do online check in a card isnt mandatory.

As far as giving a CC#, I can't remember the last hotel I stayed at that didn't require a card#. Providing it ahead of time allowed me to not have to fish it out at check in. High marks to WDW for not making me give it again when I got there, unlike every other hotel I've stayed at in the last 10 years.

As FP+ gets put into place, I am considering doing online check in so that I can make my reservations as early as possible. I am very particular about room location, so I am really hoping they will be accommodating if I need to make a switch upon arrival! We are staying at CR for the first time so still researching which area will be best for my family!
