Inquiry Submission By Odette G

Hi. I am currently traveling in Cambodia with my boyfriend. We have two nights left in Phnom Penh before we have to take an overnight bus to Siem reap (this bus ticket is not changeable or refundable unfortunately). Because of this and the few bus times available to and from mondulkiri it is not possible for us to stop there and visit the elephant sanctuary. Does anyone know how to get there in any other way than the bus’ available online?? For a reasonable price as we are students. Thank you !! ­čÖé
