60 days till we arrive at CSR - so excited!!!


Couple of questions - I noticed we can do online check-in this morning so I figured I would go ahead and do that. Things went fine till I got to the Room Request section - instead of a text box we could fill in with our requests/preferences, there were check-boxes and it said to pick up to two of the boxes. Unfortunately neither of our requests was listed - we wanted Casitas 4 or 5 (only Ranchos or Cabanas had boxes) & we would love to get a corner room (not a must by any means, but hey it doesn't hurt to ask, right?) and there wasn't any box for that. They had things like - second floor, fourth floor, near transportation, etc. Should I forgo the online check-in and just ask for what we want when we get there? Or contact my
travel agent and see if she can put in the request? I know that Casitas 1, 2, and 3 are Preferred Location & we only paid for a King Room, not King-Preferred, but I thought 4 and 5 had non-Preferred rooms?
If I can't have Casitas, what would you recommend for an older couple on an anniversary trip - Ranchos or Cabanas? Not that we don't like children, but we were hoping for a location that was a little quieter than what I've heard Cabanas are. And Ranchos seems like quite a hike to the Pepper Market and Rix Lounge. Not sure we want to do that much walking after being in the parks all day. We also love a hot tub - but are a little leery about the big one at the Dig Site (I assume there will be lots of splashing children in it) - are there smaller hot tubs near any of the quiet pools? What would you all recommend?
Lastly - what's the current story with Magic Bands and Fast Pass+? I heard on another forum that at this point, pretty much all resorts are offering these but I don't see anyplace online where I can order our Magic Bands & when I try to do Fast Pass+ it doesn't allow me to choose our dates. Will I be able to do this once I check-in? If I don't do online check-in, does that mean we won't be able to do Magic Bands and/or Fast Pass+ until we arrive?
Sorry - I know this is a lot of questions but this is a special trip for us and I'd really like to get everything squared away as best I can. Thanks for all of your expertise!!
