Where would you guys stay between the JW Marriott, the Midtown Shangri La, or the Sheraton Xixi Wetlands?

I usually stay at the Hyatt Regency but that's not an option this time. Done West Lake a couple of times...

I was leaning towards the Sheraton but can't make up my mind if the Wetlands Park is worth visiting or not? If not, the Marriott or Shangri La seem to have a more convenient location in terms of local restaurants.

Thanks!
