Lorealle is the manager at the HoJo that posts on here regularly.
They have three kinds of rooms. Standard, deluxe and premium.
Standard = 2 double beds. Most of these rooms are in the 4 pavillion buildings in the center couryard (bldgs. 3-6). None of these have views of DL, but some have pool views.
Deluxe = 2 queen beds, mostly in Bldg. 2. Bldg. 2 is the farthest North on the property so also the farthest from DLR. It takes about 2 minutes to get from this bldg. to the lobby, so I don't consider it a big deal. Bldg. 2 is 4 stories, and is the quietest and most rooms overlook the quiet pool.
Premium = These rooms have 2 queens, and are located in Bldg. 1 with a Disney View. You can see the Matterhorn, monorail, Space Mtn and ToT from your balcony. The HoJo is in the process of putting microwaves in all of their premium rooms. The top floor of this tower has vaulted ceilings with skylights which some people like, and others' don't because of early morning light issues and daytime napping issues. I have found that some of the rooms in Bldg. 1 experience freeway noise. Always best to request western-most rooms in this tower.
If you are wanting a King room, I think that is classified as a deluxe (not really sure), but most of them face the freeway in Bldg. 1, and they have some in Bldg. 2.
None of their rooms have a sleeper sofa (except their suites -- but they only have 3 of those in the entire property), but you can request a rollaway for $7. The rooms are very spacious and have more than enough room for a rollaway.
I'm sure Lorealle will be along tomorrow (during her work shift) to fill in any blanks.
