I've never heard of that happening - being assigned a room at another resort. I would imagine it was a quirky IT glitch (we know how Disney IT is...), and its probably unrelated to the fact that you stopped at the front desk upon arrival.
When you stopped at the front desk upon arrival, did they tell you your actual room number? Typically, they don't share that information until the room is coded as ready so you don't enter the room before then, and also so they can reserve the right to make last minute changes if need be. This is why people receive a text when their room is ready, even when they don't do online check-in. The text is supposed to communicate the actual room number.
Also, you went to the front desk twice but one of those times was by your own choice. You could have just waited to receive your room ready text or email, as it is in some cases. That is the whole purpose of doing online check-in - so that you can do things other than wait in line at the hotel. If you have no issue waiting in line, then online check-in wouldn't benefit you anyhow.
Yes, I think it was an IT glitch as well, however, I had to make sure I wasn't being charged for this. I didn't want to just assume I wouldn't be. One quirky IT glitch could lead to or be part of another.
The room the front desk assigned us must have been ready, since we knew the room number, but we were starving, so we went to lunch first.
Yes, you're right. We didn't have to go to the front desk at all when we arrived and could have just left our bags with bell services and done whatever we wanted until we'd gotten our room assignment text. But since there was a minimal wait to talk to someone at the front desk--I think we waited maybe 3 minutes, max--and since we were right there--the check-in area at SSR is right around the corner from the bell services area--we figured we'd just do that. So we did.
And, you know, what if the text we got during lunch, the one with the wrong resort--which text, btw, listed an actual room number--had been the only room-assignment text we'd gotten? We still would've had to go to the front desk, and if it had played out that way, I probably would've been panicking at lunch after receiving that text, thinking that we actually had no room anywhere, since (a) we didn't have a reservation at the other resort and had never had one and (b) I wouldn't've known that we
did have a room at SSR. So in the end, it all was fine.
In fact, the one visit to the front desk that involved waiting in line was the absolutely necessary visit, since we had to make sure that we weren't being charged for the other room.
All that being said, I'm never doing online check-in again, since I don't want to have this experience again. I do understand this is not a common experience, but since it happened to me, it has affected my future actions.
