You are correct, the total cost is just too much for many of us who are struggling here. I sure cant afford this for now.
Even with the offer, a family of four will cost you $235.9. and it does not include the cruiser ride at GBTB...including lunches, it will easily cost you $400.
But a s a Singaporean, does the offer sound attractive becasue it is most likely that you have been to Zoo and Birdpark...so the only likely attraction is GBTB...$400? think carefully...
