Guatemala at $303 RT

You could hang around Guatemala City, but there's just way too many enticing spots outside of it!

For starters, Antigua is just a 30 minute bus ride away. The yellow and orange-painted town is easily the country's chicest, artsiest hub, and the trio of towering volcanos that loom in the background really lend it an ethereal vibe. And if you want to climb any of those volcanos (and maybe roast a marshmallow or two while you're at it), you'll already be at the main tour pickup spot.

Just beyond is Lago de Atitlán, a massive, wildflower-covered, volcano-ringed lake. You could easily spend a week exploring all of the small towns along its coast, which range from cute touristy havens to super local enclaves grounded in traditional Mayan culture. 

But sure. Guatemala City's cool too :-)
