Don't say about promotion yet but if you want to be that rush, i would say you first need to check the rooms availability. Most of the time, you are recommended to book about 1 - 2 months in advance. Some could even lead to 3 months in advance especially during peak hours and holidays.

Looking to go to Perhentian early April. Any recommendation of a good accomodation + value for money? Budget is not an issue (although preferbly not too expensive, say, about RM400 or less per person)?

Whats the difference between Besar and Kecil? For a first timer, which is actually better?
