I'm OK with the 1st leg (I think?) & am looking at flights for $1400 return from KC to Hanoi for a month, BUT, l also want to visit Ho Chi Min City & Angkor Wat in Cambodia. I have found a reasonably priced motorcycle tour for 5/7 or 10days starting & finishing in Hanoi, but may take a train down to HCM City then ???? to Angkor Wat, but the trip back up to Hanoi could be a drag........So, is the only way to approach a RTW flight company & go KC to Hanoi to HCM City to Angkor Wat then fly back "sort of" directly from AW to Bangkok to KC???? Also, anyone who has done a similar trip please throw any info & advise at me that you have!!! Thanks for reading.
