My wife and I will be in Beijing for 5 days mid-May. Our intended basic itinerary is as follows, but we're open to suggestions:

Day 1 - Arrival at airport 2:30pm and by the time we get to the hotel there probably won't be enough time to do much.
Day 2 - Forbidden City, Tianamen Square, Summer Palace
Day 3 - Great Wall
Day 4 - Hutongs and shopping
Day 5 - Open

Any other recommendations?

Also, we are staying at the Doubletree - Hilton on Guang An Man Wai Avenue.
- Is this hotel centrally located for our touring?
- Any good recommendations for a nice dinner (perferably peking duck)?
- Where is the best area to shop?
- And is it safe to walk around at night?

Thanks for the help.
