It is also a good opportunity to have a somewhat 'unique' wedding which most of your friends and family back in the west will not have the opportunity to do so easily.
Another important factor to consider is the Solemnisation. Most Western countries will not allow a couple to be legally wed unless they are in said country for a certain number of days in order to read the bans and file for marriage (more on this later). Therefore, one might opt to get married in Singapore for the ceremony to be both religious and legal rather than separating the two (which would otherwise have to be the case).
Although Singapore has very modern venues and most of the big hotels are usually used as wedding venues, there are a few unique, colonial-style options you can consider which offer a nice breather from the modernity of the city:
The biggest pro to having your wedding back home is obviously having all your friends and family from home with you for your special day (with almost no exceptions).
However, you will have a very small contingent -if not non - existant - representation from Singapore and Asia due to cost and travel time away from work.
Another aspect to consider is your own travel time and being back home long enough before the wedding to go through last minute details with all your suppliers as well as getting over your jet lag or having your stag and hen do's - count a week before the wedding itself to get all this done!
The cost of your home-folk coming over to Asia is indeed very high for most people (especially those with children), but if you consider a 'winter' wedding in Asia, the weather will still be very pleasant here and your guests might be more than happy to get away from the cold weather for a sunny break.
