I could be misremembering, but I thought that there use to be a description of what room types were available in the housing block at each hotel. Does anyone know if there is something out there like that? Thanks!
I'm thinking you would go to the individual hotel web site to look for that.
Now, as dranthor points out, if you want to do research ahead, you visit the sites of the hotels you are interested in. The "Source of Truth", however, is the Housing Portal - once it opens.
