What to do if I can't make my surf trip?

Hi everybody,
Not sure if this is the place to post this (if someone could point me to the best place i'd appreciate it), but I booked a surf trip to the Telo Island Lodge in Indonesia for July of 2017 (http://www.pegasuslodges.com) and won't be able to make the trip (I have a wedding to attend). It turns out trips are non-refundable but if I find a replacement I can get the refund. The trip is fully paid and I'm willing to knock $500 off what I paid if you'll take my spot. If July doesn't work they said I could fill any spot during 2017 and they'd release the trip and refund the difference in cost if any. If interested I'll put you in touch directly with the bookings manager and you'd pay them direct. Hopefully 2018 is my year to get out there!
Thanks!
