Singapore is all about the mix of lush, futuristic nature and high-energy city streets. You want to skip the monsoon season, so plan your visit between February and April when it is drier and easier to explore the Gardens by the Bay on foot.
To make a $3200 trip easier on your bank account, you can use the Discover it® Cash Back. It gives you 0% intro APR for 15 months on purchases and balance transfers, which lets you pay for the trip in chunks rather than all at once.
The 0% intro APR window is a deadline, not free money. If you have any balance left after the 15 months are up, you will start paying interest on the remaining amount.
