have had 2 stays so far, both times 1 room as Diamond another as Gold.
Firstly things I enjoyed :
1. Great breakfast, large selection even by Asian standards and as far as I know the only other Hilton property in Asia that has Ice Cream for breakfast along with Conrad Singapore. The freshly pressed sugarcane juice was an unexpected perk
2. Great pool. It's a feature pool, but large enough in the middle for laps. It's also heated, a plus for me in shaded pools even in a tropical country.
3. Nice lounge. Large space and F&B options were enough for a complete dinner. Only visited once during cocktail hour and they had sushi, pork ribs, cooked fish, potato salad (with bacon pieces!) soup etc
4. Rooms were good in size & quality. Believe every room here has a separate tub & shower. Everything felt solid and well put together.
5. Located next to a McDonalds and 7-11.
Now things which I did not appreciate :
1. Not allowed to bring pool towels out of pool area.
2. Service in lounge is non-existent. Despite the 2 - 3 attendants at the desk, they do not seem responsible for floor duties. Arrived 15 minutes before cocktail hour ended and there were various tables stacked with empty plates & glasses. Also apart from a smile, they offered no verbal greeting let alone standing up.
3. Skip the Chinese restaurant. Had lunch here and food is bad.
The transfer from the airport in my experience a hassle.
1st trip we used Grab on 2 separate accounts (different timings). BOTH drivers haggled over the price and we ended up paying the Grab fare + ~150 peso extra in cash to driver.
2nd time we were traveling together and shared a coupon taxi and it was fine. Not sure why but still had to wait 20 minutes for a "allocated" taxi despite having other taxis just waiting there. Both times the journey duration was 15 - 20 minutes.
Both times we returned to the airport via the shuttle bus which was punctual but only runs every 0:30 on the hour. Journey time by shuttle is just below 30 minutes
Also just be aware there are security scans before entering the hotel. Wasn't allowed a nail-clipper ... but prefer to feel safe than sorry ?
In terms of upgrade, didn't feel this was a generous property. Similar welcome amenity for Gold & Diamond (Fruit 1 time, Chocolates another). Received pool view room once and apart from that just the standard benefits. Gold never granted access to Lounge.
