That is all depends on your budget and the size of your group. On all the gulets 2 person can accomodate in 1 cabin. So if you are 8 person than 4 cabin gulet will be enough for you butyou may choose the charter a bigger gulet to be more spacious. It is all upto you really! Keep in mind that the bigger the gulet (in cabins and in size) more spacious it is.
