Inquiry Submission By hawking1

Hi I would appreciate any advice as this is my first time in Cambodia. I’m flying into Siem reap from HCMC at 530pm. From what I’ve read, ideally I’d like to include Battambang and Phnom Penh in my itinerary but not sure how practical this is given that I’m already booked to fly out of SR 7 nights later at 350pm. After 2 or 3 days in Siem Reap, I was considering in traveling to Battambang by boat which sounds an interesting experience (reviews seem to range from horrific to amazing ­čÖé but am more concerned it will eat too much into my limited time. Any idea how long this might take in August? Would there also then be enough time to pop to PP for a couple of days and get back to SR for my flight to Danang to continue the rest of my trip in Vietnam ? Also as I’m 6ft 5 with dodgy knees i’m wondering what modes of travel would be better to/from PP ?
