The water chalet is 2 rooms of a good size, and four star quality, part of the Lexis Hotel, with the usual soap/shampoo/towels/tea/coffee etc provided. First room has toilet, sink, jacuzzi bath, shower. Second room has two double bed, desk, TV, wardrobe, fridge, and a balcony above the water with deckchairs. Fishing rods can be hired, and we sat fishing from the balcony at high tide.
The cafe/bar in the surrounding area are not great, don't bother with them, room service is good and cheap, a wide selection including KFC, pizza, sandwiches, main courses, Asian food. (no alcohol on sale).
Chalet is part of 3 block hotel complex with pool (water is warm) and pool often full of kids. Good artificial white sand beach, good for Malaysia.
TIP. Pre-book your taxi transport, Grab and Uber do not work in Port Dickson and hotel taxis are rip off, 212myr to KLIA alone. KL taxi is 150myr pre-booked to city centre. One way to get here is train from KL Sentral to KLIA (55myr), then taxi ride.
TIP. Port Dickson is a small industrial town, little to see, but this complex is great for a weekend breaks from KL city.
If you want a better beach, get a taxi south 5 miles, some nice resort beaches.
NOTE. Beaches around Malaysia are not great, the water no suitable for swimming in.
NOTE. This room is serviced by the hotel staff, cleaned every day, room service delivered, etc.
