We just stayed in Sheraton the past weekend. We arrived hotel on Sat at 11:30 am. Rooms (we booked 2 rooms) are not ready so we went to Yantian Seafood Street for lunch. Price was not expensive (RMB400 for 4 adults and 2 children) but seafood was just so so. We returned to hotel at 1:30 pm and rooms were ready for check in.
The swimming pool is great, very large and beautiful. Our sons enjoyed the water slides but the slides only open at 10 am-12 noon and 3-6 pm. The private beach is also good. Not many people, wave is not big and the sand is soft.
We had buffet dinner at hotel. Selections were not a lot but food was quite good.
If you do not eat at hotel, there are several restaurants across the road opposite to Sheraton.
Overall we had a very peaceful 2D1N journey at hotel. We'll go again next year and we will go to 東部華僑城 which is very close (may be around 10-minutes by taxi).
