We booked the 3 day, 2 night option for $200 each on hotels.com and were happy with our decision. Room was clean, in good shape, with powerful AC, comfortable bed and with closet-style shower and toilet. Fairly small, as expected, thin walls, and some creaking floors. No in-room safe or mini fridge.
Meals provided a crazy amount of food and courses...quality was fine with some dishes better than others. Company should reduce portions and focus on providing just a few excellent courses. Breakfast was nice with coffee, fresh fruit, eggs, bacon, toast, and pho. 2 small waters per room per day and coffee were provided and everything else was extra and overpriced by SE Asia standards (USD $3 beer, $2 small water, $6 cocktails/mixed drinks)
The scenery was wonderful and the common areas were very nice to sit and soak it in.
Staff were friendly, helpful, and service was great throughout the trip.
The excursions from the boat were all excellent. The kayaking spots were great and we had 2-3 hours between the three days (with option to ride in a bamboo boat at the first stop if you prefer). The cave stops were very cool: the first (on our middle day) was smaller and more intimate and involved some scrambling. The cave on the last day (Surprise cave) was large, well established with walkways and stairs, with impressive formations and beautiful views.
