Eighteen hotels, four categories
The Room Index is an independent reference to eighteen hotels, grouped into four categories. Each entry describes where the house stands, how the building and its shared rooms are arranged, and what is worth settling with the hotel in writing. There are no prices here, no stars and no ranking of one house against another.

Entries are written from hotel material, maps and published sources, then dated. Nothing here is sold, booked or recommended over anything else. Where a house belongs to a group with several addresses, the entry names the one it describes. How this is made.

A note on categories
The four categories describe how a house works rather than how good it is. A hotel appears in one category only, and no entry is moved between them for effect. The short definitions below say what each word means on this site, since all four are used loosely elsewhere.
Ice Hotels. Mountain lodges that run a winter season, where snow governs access, opening dates and daily arrangements.
Capsule Hotels. Houses built from small repeated rooms or cabins, usually with shared washing rooms and a shared lounge.
Casino Hotels. Canadian resorts described here only as hotels: their halls, restaurants, spas and grounds.
Art Hotels. Houses where the building itself, its conversion or a collection kept in it is the point of the stay.
