As shortie1848 mentioned, they don’t help with the room blocks. However, there really is not much to blocking rooms at a hotel. First the how:
You can call hotels near The Club @ Key Center individually to see if they have availability for your dates. Here are some hotels nearby with telephone numbers and addresses in case you want to take a look:
Cleveland Marriott Downtown at Key Center
127 Public Square, Cleveland, OH
Hyatt Regency Cleveland at The Arcade
420 Superior Ave E, Cleveland, OH
Renaissance Cleveland Hotel
24 Public Square, Cleveland, OH
Hampton Inn Cleveland-Downtown
1460 E 9th St, Cleveland, OH
Holiday Inn Express Cleveland Downtown
629 Euclid Ave, Cleveland, OH
Radisson Hotel Cleveland-Gateway
651 Huron Rd E, Cleveland, OH
DoubleTree by Hilton Hotel Cleveland Downtown
1111 Lakeside Ave E, Cleveland, OH
Embassy Suites Cleveland – Downtown
1701 E 12th St, Cleveland, OH
The Ritz-Carlton, Cleveland
1515 W 3rd St, Cleveland, OH
You can call each one individually or you can go online and block rooms on GroupTravel.org. Online is way faster but you can try whatever suits you better.
Regardless of how you block rooms, here are things you should keep an eye out for. Try not to block rooms where the hotel makes you sign an attrition clause. This is where the hotel will charge you for unused rooms. So if you block 30 rooms and only 20 get reserved, the hotel holds you responsible for the 10 that were not.
Instead, look around for a hotel that offers a courtesy room block. This is the kind of room block where you don’t pay a deposit and you are not held responsible for unused rooms.

Also, many hotels offer a free room for every 20 or 30 rooms you block. Make sure to ask their complimentary room policy too.
