Looking for hotel recommendations in Shanghai. We have status and points to use with both Hilton & Marriott, and are trying to decide where to stay. We are a couple, mid 30s, live outside of NYC, and are traveling for pleasure, no children. We aren't big drinkers, but we enjoy having nightlife nearby so we can "people watch" at night. We are comfortable taking subways or using cabs so long as the price for a cab isn't as outrageous as the $60USD we paid to go 3 miles in Switzerland last year! We will be in Shanghai for 2 nights, so we are looking for a hotel that will allows us to sightsee, shop (local markets, no overpriced designer stores), and enjoy the local culture during the day, and then allow us to hit the town at night without making transportation a major hassel. I see great reviews for the Waldorf, but I don't want to be too quick to pick the #1 rated hotel just because the rooms are beautiful. Any advice is much appreciated. Thanks in advance!
