New Orleans is best in late spring. The heavy humidity hasn't settled in yet and the city feels more manageable without the Mardi Gras crowds. You get to spend your mornings with coffee and beignets, then spend your nights catching live jazz in the Frenchmen Street clubs.
If you want to handle the $1200 cost without paying interest, you can use the Citi Simplicity® Credit Card. It offers 0% for 18 months on purchases and balance transfers from date of account opening. This lets you stretch the payments out instead of hitting your bank account all at once.
Remember that the 18 months is a deadline, not a gift. If you still have a balance on the card after the intro window ends, the bank will start charging interest on whatever is left.
