As the final stop on our trip, we decided to book an all-inclusive beachfront hotel, and it couldn't have been a better choice—it was absolutely fantastic. The weather was perfect, and since it wasn't peak season, it was practically empty, so we had the whole place to ourselves. It's a 5-star hotel with water slides, a casino, a shopping center, a spa, and because it's so big, they take you from place to place in buggies. What they told us upon arrival was: "You don't have to make any effort; there are always buggies available to take you wherever you want." The service was wonderful from the moment we arrived.

There's another hotel called Garden that's more geared towards children. We visited it, and you should definitely avoid it if you're traveling alone. It's not as spectacular, nor does it offer the same level of service and attention as the Grand.

The hotel spa is called a sauna, but it's a mini-spa with heated pools, an outdoor pool, and a sauna—very cute and included in the hotel price. You can go as many times as you like. When we arrived, they took us to separate changing rooms, gave us bathrobes, towels, and slippers, and when we were all changed and waiting outside for each other, we realized they were taking forever. It was because there was one room for women and another for men. It was very strange for us, and we didn't enjoy it the same way we would have if we were together, but even so, we relaxed a lot. We were completely alone in each spa.

There is a shuttle bus (free but with tight schedules and packed with people) that takes you to the tourist spots, so we went to the amusement/water park (VinWonder), a mega shopping center (Grand World), and the Safari.

VinWonders: Entry 987.531 VND (around €32/person). We bought it at the hotel because you have the advantage that by doing it with them you can enter and exit as many times as you want, whereas from the park's own ticket office or from the internet you cannot.
It's an amusement park and water park combined; the entrance fee includes access to everything. There's a locker area at the water park where you can rent a ticket for 100,000. VND (around €3), you leave a deposit that they later return. It's worth it because you don't have to worry about anything and they even give you a waterproof phone case. + shower gel + shampoo/conditioner. 

Grand World: A huge shopping complex with a navigable canal running through it. It's actually quite beautiful. It gets very crowded in the summer, so it must be overwhelming.

Phú Quc combines very well with Hanoi because it is usually the perfect relaxed ending after a tour of the north among culture, temples and traditional neighborhoods, and with Halong Bay because it offers the ideal contrast between cruises, karst landscapes and a few days of beach and rest in the south of the country.
