hi molly,
if thats the case, then stick to changi and raffles place lor.. cant be greedy to go for soooo many OD places.. u may not have time.. and if you may, you may end up looking tired.
i aint too sure of such places in raffles or sentosa. dun think its widely mentioned in this forum. if your PG dunnoe, then just stick to 2 OD will do...
