Nah - not that much. The boat is quite reasonably priced - around $3800 or so for the 12 day trip, according to the http://www.bilikiki.com/rates.php">Bilikiki website</a>. Plane tickets run around another $2k, and then there's about another $1k of extra expenses between hotel stays, tips, etc. Then figure in extra dive equipment and camera gear (can't run to the dive store if you lose a mask in the middle or the trip) at 500-1000, so.... ~$8k.....
dang... maybe it was close to that.... :)
Oh, and I [B]do[/B] have a mortgage!
