If your first request is for a refurbished room, I would recommend:
1. when you do online check-in to only request sections that are refurbished. (70's, 80's and 90's right now and probably when you arrive too.)
2. Call Pop and request a refurbished room
3. If you have a Touring Plans subscription, request a room in a refurbished area.
Refurbished rooms are getting easier and easier to get now as over half of the resort is refurbished and some of the remaining rooms are closed for refurbishment now.
Your arrival time should have nothing to do with what room you are assigned, the steps above have a greater weight than arrival time. Room assignments are done a few days before you arrive so your initial room assignment will be based on the information you have submitted above. International visitors cannot receive texts but I know they email Canadians and hopefully other International visitors too.
