Yes, Madison Square Garden is in a very busy, very convenient area of Manhattan. I'll try to attach a map. MSG is the "donut" next to the taller building pictured on the map. You should have no problem finding someone to visit you in that area. Alternatively, you are within easy walking distance of many popular hotels and meeting places. (No need to take a cab and spend more time sitting in traffic than having fun.)  

It shouldn't be a problem, but be aware that "Madison Square GARDEN" is different from "Madison Square" so be sure to use the whole phrase. (An earlier MSG was at Madison Square. When they built the new one, they kept the name.)

Your visit will span St. Patrick's Day (Mar 17). There is a huge, popular parade in NYC on Mar 17. It starts at 44th St and moves north. MSG is at 34th, south of the starting point but the parade creates a giant traffic jam beyond the route. Plan your schedule carefully.

I'm a sweet and intelligent girl who absolutely loves dinner dates, and can appreciate sensuality in and of itself. I'd love to meet you in March!

Hello Craig.  

You certainly sounds very nice. I think we could enjoy each other company.
I'd love to accompany you and show you around while you're in NYC.

Kisses.
Vanessa.
