Hi gambit,
tiger dun sell beer directly to the public. u can go thru their agent... one called Thong Huat.
my situation is just like u! i dun have much choice for hotel as my hubby's family and friends are all in australia. but we manage to have 22 tables though. likewise, my parents didn't like the idea of having it on sentosa due to inconveniency.
i have emailed some bus-service co. and they charge about 300+ for about 4 trips. U will have to indicate the timing for your private bus service on the wedding card. if those who are late will have to take the beaufort bus instead. for your case, u've only got 10 tables, so much easier to coordinate.
however, if u think again... most guest will take a taxi to a wedding unless it is absolutely near the mrt station... so dun bother too much. old folks tend to grumble alot before the big day... when they see how classy it's gonna be... they'll forget it. suggest that u bring your folks to see the place. i'm sure they'll be overwhelmed like mine.
oh.. and let the non-singaporean do the talking and sell the idea....! it helps
