Hi, I am travelling with my family including 2 kids (12 & 5) in the month of August 2016 to Malaysia, Vietnam & Cambodia. I have booked all the flights and accomodation well in advance. I will be staying for a couple of in KL and then head out to Penang for 6 nights. Then onto Vietnam for 4 nights (Ho Chi min and Nha Trang) before flying out to Cambodia (4 nights) and back to KL for 4 nights. I have looked at some attractions that I plan to visit when I am there but I haven't booked any of the trips. Is it advisable to get the hotel's assistance in booking those trips? Also any advice / tips of the type of currency to take and also if we need to be aware of anything? Any recommendations on local attractions?
