Better to contact WWFHK (
maipo@wwf.org.hk) or Agriculture, Fisheries and Conservation Dept of HK SAR GOVT directly about permit issue.

Not sure WWFHK still provides accommodation at their Peter Scott Centre. Pls contact them.
Other options maybe Regent Hotel at Shatin (20 km away fr Mai Po), Harbour Plaza Harbour at Tin Shui Wai (about 15 km fr Mai Po), or Sun Kong Hotel at Yuen Long (about 5 km away)
Good luck and have fun
