The Negative Part:
Upon arrival, our room had too many mosquitos. When we requested the staff to change the room, they said that they did not have any room available in the same category. Then, two people came and sprayed a lot of mosquito spray in the entire room. The presence of the mosquitos and the smell of the spray made it impossible to stay in the room. Upon requesting again, they magically had another available room in the same category (room next door). When we went to see the other room, it had exactly same problem.
Then the staff told me that they would upgrade us to a higher category, since that room had no mosquitos, so we agreed to stay in that room after checking. However, they asked me to pay the difference in the price. It took me some effort to explain to them and get them to agree that this was not an upgrade I had requested for and so I would not pay for the same.
All this happened at 10 at night, after we had had a full day of trekking at Erawan!! Phew!!!
The Positive Part:
The new room was very spacious and up to date with all amenities. In the morning, the staff cooked some food for us specially to cater to our requirements (we are vegetarian).
