“Luxury” and “ Good Value” don't necessarily go hand in hand…
However, its generally known that many Asian countries have a lower daily cost of living, so expenditures for food/accommodations/alcohol etc are less, therefore you can stay longer and get better value for your money
Look at destinations like-
Thailand, Malaysia, Cambodia, Vietnam, the Philippines, Indonesia, Laos, Sri Lanka, Goa, etc …
You would have to research these and weigh the daily expenses against higher Airfare costs, as youd be flying a considerable distance from the UK …
All of these Destinations have their own Forums here on TA with a Hotels listing section where you can research accommodation choices and see their nightly rates and inclusions/amenities
