I just back from JB. The Toyrus 30% voucher still can use. The weather was good there not very hot and much better than HK. The SEA and waterpark can use BOC to have 20% off. Many many people go to the SEA and waterpark. I go there before 10:00 still need to qute up inside for more than 20 mins to watch the fish... No traffic jam just 45 mins from airport to JB. No need to wait cross from SGP to JB at all.
