I really wish there were a site which consistently listed all the basic factual data about each hotel in a uniform matter:
- size in square meters (or feet) of each class of rooms
- whether internet access is available in rooms (all rooms or just certain rooms)
- whether the internet access requires a separate fee (and what that fee is, if you are pricing rooms)
- whether there is a fitness room on premises
etc

I'd also like to see an industry-wide standard of hotels posting on their websites when construction in or adjacent to the hotel is planned or underway. Hotels that do not have websites, or smaller hotels that are not able to update their websites frequently enough to incorporate this information, should notify anyone who is booking a hotel of this information at the time the booking is made and allow the guests to cancel their reservations at the time of booking due to the construction.
