Ok, I am getting ready to pull my trip together (appt. with Mark and Leon) but I need some advice. Where is the best place to stay? I would love to be able to walk out our hotel and be in the middle of bling! 5th Ave.? 7th Ave. Park or Madison? Upper 50''s, lower 50''s. Something tells me not to stay in Times Sq. Right? Close to the park or Rockefellow Center? OR close to the diamond district? I''m not looking to spend $500 per night, but I think $300 would be ok. Any ideas?
