“Exclusive hire includes use of up to 28 bedrooms; eleven in the Great House and 13 Balinese-style houses, a beach villa and bunk rooms dotted around the island, accommodating a total of 56 adults and 14 children.”
Just in case you wanted to rent the entire island. For you, the Mrs and 54 other adults.
I recall years ago thinking this was not really a bad deal because it worked out to around $1000/couple/day.
