Only 4 days in Shangri-La and one day to take wedding photos - where should we go?

Hi! My fiance and I have decided to have our wedding photos taken in Shangri-la bc of its reputation for its magnificent and beautiful scenery but we only have 4 days for the visit and our photography is available to take the photos only for one day. Bc we only have 1day for the photo shoot, we must be choose carefully where to go for the best photo spots. I did some online research and there is so much information, I feel a bit overwhelmed. Can anyone recommend the best places to shoot photos in or around the city and whether the lakes (Bitahai or Shudu) are close enough for us to fit them into our one-day shoot as well? If the lakes are close enough, we would love to hire a horse for the shoot as well :) We will definitely be hiring a private car, so hopefully this will help with the travel time. Any recommendations as to where we should go would be much appreciated! Many thanks in advance!
