Unsure if I should have dealt with this situation differently, trying to check in to the St Regis Singapore this morning.

I used mobile check in yesterday, said that I had been upgraded to a suite in the app. I also put in my check in time as 1100.

When I arrived at the hotel, I was informed that check in is at 1500 and the room is not ready. I also got downgraded (but still an upgrade from the room I booked) to another room type. They said they will have the room ready by 1300.

Should I have confirmed my check in time with the hotel before? I assumed that because my mobile check in was accepted for 1100 it would be fine.
