You could check other topic in BK. Actually, you could buy the package through travel agents, HKCTS (中旅社) is reliable.
Transport:
3 kinds of transportation available from HKG to Chime Long: vessel, long dist bus or intercity through train. For me, I like taking intercity through train, more comfortable and faster than others.
Hotel:
Except Chime Long Hotel, you can also stay in 祈福酒店 or 星河灣酒店.
Parks:
3 theme parks and a circue in Chime Long: Water Park, Chime Long Paradise, Safari Zoo and Circue.
If you stay 2D1N, you could choose 2 from 3 parks in day time, and watch the circue at 7pm at your 1st night.
