Costa Rica's cloud forests feel like another world. Hanging bridges, thick mist, and miles of zip-line cables running over deep valleys in Monteverde. Going during the green season from May to November means lush views, smaller crowds, and cheaper rates on lodges and tours.
A typical trip with flights, stays, and activities usually runs around $1900. If you do not want to drain your savings account all at once, you can spread the bill across time without racking up interest charges.
Keep in mind that 0% interest is an intro window, not free money. If you still have a balance after 18 months, the card's standard variable rate kicks in on whatever is left, which makes the trip more expensive fast.
