I'm sorry your trip is not off to a good start. For future reference, and for anyone reading this, here is what I recommend:
1. To request Connecting Rooms - Call WDW at least 1 week in advance and have them write "Connecting" rooms. Make this your only request. Rooms are assigned about 4-5 days before. If you wait to call the day before, your rooms have already been assigned. Connecting rooms are *NEVER* guaranteed. If you *NEED* connecting rooms, book a 1-bedroom or 2-bedroom.
2. If you do not get your connecting room request - Ask if you could be moved to connecting rooms the next day. With people moving out, hopefully they can accommodate you.
3. Always do online check-in - Check-in in person lines are always long. I always go straight to my room.
4. Your MB will only open *your* room - When traveling with more than one room, if you have an old MB from one of your family members in that room, you can use that one to open their room. For example, if your 5-year old is in the other room, and you have an MB for that child from a previous trip, you can use that to open the room.
We went in October and really enjoyed our stay in the Ranchos. The only issue we had was the buses, which were the worst, by far, in 17 onsite trips in the past 10 years. Thank goodness for Uber/Lyft.
