Nuts! This is what happens when one goes away for a few days....
This may not be the place, but I have four tickets to Cleveland for sale. Willing to split into pairs. Section 108, row 8. My friends and I went ballistic getting tickets and were, shall we say, a little too successful.
Also, the arena/downtown area is nice enough. I wouldn't stay at the Marriott (not worth the price). But, be careful at the bus station. Not too close to downtown, and not in a great area.
Finally, you have to check out the Warehouse District. Go to the Metropolitan for dinner, and check out the Blind Pig Speakeasy. And don't wear tennis shoes!
