Why not stop at KL, Singapore, Go Thai even.
I think the saying is more bang for your buck

That's what I did a while ago.
Found a lot of Australian prices were double the UK. Then went to Singapore and things were around half the price. After that, Kuala Lumpur (Malaysia), and things were half the price again.
(Think it was something like £200/hr in Australia; £50-£60 for an hour in Hong Kong; £80 for an overnight in Malaysia etc.)
We do get a pretty good deal on a lot of things over here compared to Australia, the USA etc. even though we moan about how something went up from £1 to £1.05 overnight
Although at present, getting to some of these places is hard and can't say for certain if the women are there due to travel / Visa etc. restrictions.
Kuala Lumpur, at present, has some £19 a night prices at various hotels such as some Hilton branded one. Dirt cheap if you're there for a couple of days and pick up a girl in the Beach Club (or wherever these days).
