Just returned.
As has already been said KL was a (mostly very nice) large Asian city, cheap food and approx £3 for a beer. Much nicer than I imagined it was going to be, especially around Petronos towers.(money area obviously)
Easily half prices of major uk city, street food / hawker food halls especially great.
Got around via uber, dirt cheap.
Also went to Cambodia (Siam reap) for a week, £50 per night (for 2) in a luxurious hotel 4* b&b, pool etc.
Pub street $0.50c for a beer, $3 cocktails, $5 meals, awesome food and bars.
Angkor Wat was great too, Very humid / hot tho…
Was 3rd world-ish around Angkor (but that was expected tbh).
Just for context, not sure if I’d take young kids tho unless adventuress type (too hot maybe?)
