Thank you Butch for the helpful information on the wiki.
It sounds like there's some misalignment as to how much to guidance/detail to expect written out. In previous years, volunteer organizers went out of their way to describe in extreme detail how to get to the accommodation/venue, even with recorded video walkthroughs. That was great, but should not set an expectation for future organizers to do the same: it's hard enough to organize a conference like this, without meeting all these expectations.
Whenever there are specific questions, it's of course always welcome to ask people - for example through this list. Perhaps the
Rome2Rio link in the wiki page linked earlier will give you this kind of 'walking instructions' - but indeed entering the address in Google Maps may also be helpful. I can imagine that relying on live access to internet is a bit scary (will your phone work?) so looking into it in advance sounds helpful. It looks like a straight metro ride with a short walk along two streets.
Andy, if there's anything specific that you need beyond that link, feel free to clarify what that is, and what gives you uncertainty about this. I'm going to assume that the MRT station inside the airport is easy to find, and that the walk is acceptable. If you do find information lacking on the wiki and you figure it out (with or without help), I hope you'll feel free to either edit the page, or suggest it on the talkpage as an improvement.
Overall, I hope that as a community we can lower what we "expect" from the organizers to take care of - because the increasing list of things they have to arrange make it nearly impossible for future conferences to be organized in an affordable manner.
Warmly,
Lodewijk
