Thanks for your help. We've been to New York many times and like these above-mentioned areas very much. I've already stayed in Hell's Kitchen area (near 10th Ave.) and found we had to walk quite a lot to get to and from the hotel. Many of the attractions we visit are south of 23rd St or Brooklyn but generally, the Soho/Tribeca area tends to be more expensive. I'd rather go for approx $100 than up, but can stretch it to $120/125
On the other hand, UWS is also an option. I've stayed on 86th St before and the area is relaxed and convenient as well. I wouldn't like to go farther up for the reason above mentioned though if the price is right, I could change plans.
There's so much to see in New York that basically, all areas would work one way or another. Also, we're theatergoers but I don't like to stay in the Times Square/theater district area, so Bryant Park is an alternative to be near the theaters but not in the middle of it all.
The Port Authority/ Madison Square Garden area is off limits. Don't like it. Only visit to go see a show.
Hope I've given you plenty of information to help us. You've been very kind. Thanks a lot.
