We'll be going to the Frick Collection first. It small enough to enjoy without feeling overwhelmed. And there is a music room I know Rob will want to explore.
Just a few blocks north and we'll go to the Guggenheim Museum. They have a café where Rob and I can have a bite to eat. Sandwiches, water, perhaps a coffee. Depending on how we're feeling, we may then walk a little further north so I can show him where I used to live. We can catch the cross-town bus from there and take a bus south to our hotel or catch a cab. Or we may just head back to the hotel after going to two museums. I've warned Rob New York is a walking city. I don't know how seriously he is taking my warning. I'l have to tell you how it went when we return.
