My partner and I recently spent 4 nights at Grand Centara Beach Resort, Krabi. The resort was beautiful...the staff were friendly and as helpful as possible (there were few staff though that spoke english). The room was beautiful, spacious and well appointed, just as the photos had indicated.
The only problems we faced were on the day we arrived at the Had Nopparat Thara Pier we were greeted by a staff member advising the tide was too low for the shuttle boat to run until around 7pm that evening (approx 4 hours time). The only other option was to be dropped at their office just down the road and walk through the bush and along Monkey Beach. They took our luggage and delivered it later on. Luckily we took our carry-on luggage with us as we had a change of clothes so we could have a shower, change and enjoy a drink and dinner. Most of the other guests were still waiting around in reception until after 7.30pm for their luggage and still in the same clothes they had trekked through the water in earlier to get to the resort.
The only other problem we had was our room key was faulty. On 2 days in a row we had been out and returned to our room later on only for the key not to work. We had to then walk down to reception and advise our key was not working. They then had to reset and give us 2 new keys. Thankfully this only happened twice and not everyday.
The last negative was the food in the onsite Thai restaurant was not up to a quality I consider in line with a resort. I ordered a chicken fried rice and whilst eating the meal i found a couple of pieces of chicken that were not cooked properly, luckily i spotted these pieces and did not eat them avoiding serious food poisoning.
Overall the resort was great. The monkeys were a fantastic feature, especially the "Monkey Trail" it was the only way to get to Ao Nang other than the shuttle boat. We walked this trail a couple of times and there were monkeys everywhere. I probably wouldn't walk this trail at night though, even though it was well lit it was not built very well and the monkeys are literally everywhere and they will steal your sunglasses or hat off your head and take things out of your bag if you are not careful. I think it would be much easier for them to take things from you at night. Awesome resort, we booked through Expedia and got quite a good deal, definetely good value for money.
