from that I don;t think SG is for us though we are really only going due to it being a good route to get to Krabi and flight availability on the new BA club suitesIf you don't like HK for the reasons you said then you won't like Singapore. Singapore is like HK without the edginess. Singapore didn't go through the same evolution during the start of the 20th century the same way as HK did. Singapore for example did away the street food scene (Dai Pai Dong) and pushed them all into Hawker Centres. Cleaning up the street and also preserving them. Hong Kong didn't did that so much as they just limited the licence of them and letting them die slowly.
The way they handled housing too means more home owners in Singapore in better accommodation.
Singapore is a cleaner, less edgy version of Hong Kong. Singapore is like Hong Kong island all over, without the Kowloon (grungy) and NT (nature) part.
