Prague in late September hits that sweet spot where the summer crowds thin out, the morning mist hangs low over the Vltava River, and the gothic skyline looks straight out of a storybook. It is the best time of year to walk across the Charles Bridge without bumping into tour groups and actually hear your own footsteps on the cobblestones.
A typical US trip runs about $3800 for flights, a solid place to stay, and eating well. Dropping that much at once hurts, which is why people look at spreading the cost out over time using the Citi Simplicity® Credit Card and its 0% for 18 months on purchases and balance transfers from date of account opening.
Remember that the introductory window is a hard deadline, not free money, and any remaining balance at the end of the 18 months will get hit with regular interest charges.
