A word of caution to conventioneers - come prepared!
You will need to bring an open mind, a sense of humor, lots of patience, your own clock, ear plugs, bath mat, removeable safety handrail, sweater, ice, and a word of appreciation for a hard working hotel staff that is doing their best to cope with a 40 year old building. My wife & I just spent 4 nights at the Blake with just under 500 other miniature enthusiasts freezing in the beautiful & large ballrooms and sweltering in our cramped, poorly redecorated and unsafe hotel room. The new bed linens couldn't make up for the fact that the air conditioner in room 620 blew only warm air until it was serviced. But with the slightly cooler temp came a constant stream of water down the wall to the carpet. After showing the front desk folks pics of this, they moved us to 1118 with a working AC & dry wall & carpet. 
ROOM SAFFETY ISSUES: The emergency evacuation map on our first room door was not accurate. Getting into & out of the shower is a real slip hazard without a handrail to hold onto. Mildew and mold from a ceiling mounted AC unit is another. Because the lock on the glass door to the bathroom door is mounted backwards, it is possible to lock yourself into the bathroom if you're not careful! Of the two stairwells on each floor, only one will lead you to the lobby. The other one goes to the basement & then back up through a storage area to a loading dock. There were no firehoses in the storage units on each floor.
OTHER ROOM ISSUES: The I-Home radio & I-Pod player clock could not be set to the correct time. While we could not hear anything from the adjoining rooms, we were awakened numerous times by sirens, motorcycles & trucks on the nearby expressways. The bedding is firm & the room is crowded with a wrongly sized desk. (The interior designer should be fired!) The bathroom is more than compact. It helps to be a contortionist in order to reach the toilet paper. I must say that the electric mirror in the bathroom was unique.
HOTEL STAFF: We greatly appreciate the efforts of Elsie & Racquel at the front desk and Wayne & Neil on the maintence crew. They and their fellow employees had the added stress of a crew from NY headquarters being there for several days.
There is a working ICE MACHINE on the 14th floor. Hopefully, the others on the 7th & 10th floors will be in place & working when you get there.
The BREAKFAST BUFFET was great! The food was hot & tasty although the restaurant was cold along with most of the other public areas.
We have been told that the north tower is being renovated & should be open soon. In the meanwhile, come prepared!
