Dublin gives you centuries of history right alongside the wild Irish Sea. You spend your mornings walking cobbled streets near Trinity College and your afternoons on the cliffs in Howth, taking in the salt air. Autumn is the time to go, when the summer crowds thin out and you can actually hear yourself think in the pubs.
A typical trip runs about $2100 once you factor in flights, a decent place to stay, and a few pints of stout. Booking those flights four months ahead helps lock in better rates before the airlines start hiking prices. When you are looking at how to spread out that cost, you can use the Citi Simplicity® Credit Card to manage the payments over time.
That 0% window is a deadline, not free money. If you still have a balance left when the 18 months are up, the remaining amount gets hit with the standard interest rate.
