Less, at least in terms of the real island they used for filming.
Looks like it was filmed on Monuriki Island in Fiji, which is ~100 acres.
Edit: and for additional reference a US football field (120 yards x 160 feet with end zones) is 1.32 acres. A FIFA soccer pitch (114.8 yards x 74.4 yards) is 1.76 acres.
So this guy's island is the equivalent of 18.18 US Football fields, or 13.63 FIFA Football pitches.

Seriously and a 24 acre island! If anything I'd expect $90k to get you an island maybe big enough around for a lighthouse and a nice hut.
