            Bad service, terrible receptionist”

            Very bad service and staff

            That's really a terrible experience. When we came to Do Son resort, the receptionist told that they have not our reservation, sales team works only until 4.30 p.m and after this time, they don't care about reservation of the resort. She also told that although we booked through Agoda and we paid already, they have the right to reject our reservation. I think she doesn't know about her work and about hospitality industry. That's such a unprofessional receptionist, bad service, we can't not take a seat at lobby in calling Agoda to solve the problem. Finally, after calling Agoda and 2 hours waiting, we can enter our room but that's sure we will not return to this resort and recommend others tourists not to book rooms in this resort.

            Waste of Money!!! Overpriced and dirty”

            swimming pool

            We were severely disappointed in our stay at the DoSon Resort. We chose it because it had a pool, but this was the only redeeming part. For a large hotel who claimed 4 star status, it was dirty, no one spoke english, poor service, and my son and daughter in law had rats in their room one night, and had to move to another one. They have an 18 month old baby and were afraid the rat would get in his travel crib. I realize that we were there in the off season, but frankly the place was dead and not worth spent we spent for three nights. We also had to watch every bill for food or drinks as they tried to double the amount. This is unacceptable for a business as far as I am concerned.

            ハイフォンでカジノができるホテル”

            このホテルの良いところは、カジノがあるところと、当エリアの中で日本人が抵抗なく宿泊できる環境であること、手頃な価格、くらいかな。

            카지노는 이용자가 베트남 현지 사람들이 많은 편이며, 외국인들이 좀 돈이 많은거 같으면, 옆에서 팁을 달라며 귀찮게 한다. 카지노 딜러와 친구라면서 딜러에게 팁을 주지말고, 본인에게 다이렉트로 달라고 하며, 우스운건 딜러도 그렇게 하라고, 종용하는 것이다. 참 불쾌하고, 어이없는 상황이 발생하는데, 이런 카지노는 어디에도 없는듯 하다. 아마도 카지노 딜러들과 삥 뜯는 애들과 한통속인거 같다. 호텔 세탁비는 다른 호텔에 비해 두배는 비싼듯 하고, 리셉션을 제외한 나머지 직원들은 친절하지 못하다. 그리고, 택시를 이용하려고 호텔측에 요청하면 호텔 직원으로 보이는 유니폼을 입은 사람들이 택시가 아닌 일반 차량을 가지고 와서 불과 5~6km 정도밖에 안 되는 곳을 30만동씩 받는다. 스파가 유명하데서 두번 방문하긴 했지만, 체계가 잡히지 않은 서비스로 그저 그닥? 두번다시 이용하고 싶지 않은 호텔이다.

            조용하고 조용합니다.”

            주위에 아무것도 없습니다. 조용합니다. 뭔가 잃어 버리거나 할 염려는 없습니다. 아침 밥은 뷔페로 제공되며 식사후 산책과 카지노 즐기는데 좋습니다. 가끔 비치로 내려가서 해변가에 앉아 쥬스 마시면서 망고 먹는 것도 좋습니다. 여럿이 함께 놀려와서 시끌시끌하게 지낼 거면 비치 쪽 호텔이 좋고 그냥 조용히 시간 보낼 거면 리조트 호텔이 좋습니다. 프런트에 영어를 잘하는 직원들이 응대해 줍니다. 수영장에서 수영하기도 좋습니다. 다만, 투숙객 중에 중국인들이 많습니다.

            Lần đầu lưu trú tại đây. Cơ sở vật chất có vẻ đã xuống cấp theo thời gian nhưng vẫn chấp nhận được do hàng cao cấp. Khá vắng khách dù đi vào dịp cuối tuần. Chắc do giờ có nhiều ks mới hơn. Nhân viên phục vụ ok Khu vui chơi hơi bị hạn chế và xa Hồ bơi ok Phòng có bồn tắm riêng tốt
