Is the package offered by Eternal East?
Seems not much different than buying separately:
Delux Room+早buffet = $1,100(Tue-Thu)/$1,200(Fri-Mon)
EEBus = @$65 x 6 = $390
晚buffet = @$200 x 2 = $400 (Kids 6-12 @$100, <6 FOC)
For me, it's more flexible and less expensive to travel by KCRC and then Taxi ($80), though the jounery was quite scaring as you know the bad habits of ShenZhen taxi drivers.
Also, you can call to Sheraton's reservation centre (23173388) to book the room direct, only need to provide the credit card no., and may cancel the booking before 6pm of the arrival date without any charge.
Not all facilities had been open yet - only indoor and outdoor swimming pools, gym, kids play room. The beach has no umbrella/chair, the sand is fine but the water is quite muddy as there is a construction site next to the hotel.
