You want to walk among the cloud forests of Monteverde, listen to howler monkeys, and watch the rain roll over the canopy. Going during the rainy green season means fewer tourists and much lower hotel rates across the country.
A typical trip runs about $2100 once you factor in flights, places to stay, and getting around. Spreading that cost out over time makes it easier to manage while you lock in your dates.
Remember that the 0% intro APR for 15 months on purchases and balance transfers is a hard deadline, not free money. If you still have a balance left when those 15 months end, regular interest kicks in on what you owe.
