Grammy Award-winning duo A Great Big World is bringing its unique and inspiring sound to Boston next month (Brighton Music Hall, March 6). Ian Axel and Chad King, both 30, met more than a decade ago in a music publishing class at New York University. Their song “Say Something,’’ which they sang with Christina Aguilera, became a huge hit. Axel, who is from Fair Lawn, N.J., and King, who hails from Port Charlotte, Fla., now call New York City home. We caught up with the talented musicians, who have released two albums and are working on a Broadway musical, to talk about all things travel.

Favorite vacation spot?

Axel: I like it tropical. I went to Hawaii a long time ago and cannot wait to get back there. It just felt so prehistoric-like and just kind of gave you a historic perspective . . . being on this rock in the middle of the ocean. My fiance likes the ocean and we like going on vacation and getting pampered – getting a massage, laying out by the pool and drinking a tropical drink. . . . So I’d say anything tropical. I’m going to St. Lucia in the summer, so I’m excited about that.

King: I really like tropical weather. I just recently was in Florida for a week and a half for Christmas and I was on the beach at a hotel that had a balcony. It was beautiful, feeling the sun every day, every morning. . . . And while that was great, the West Coast sun feels better on my skin and I would love to vacation in Hawaii. I know that Ian was raving about it. I feel like it’s in the stars for me at some point.

Favorite food or drink while vacationing?

Axel: In those tropical places, I really love coconut. I love drinking coconut water out of a coconut, or a coconut smoothie [when they] blend the coconut meat with some fruit. I’m not really a big alcohol drinker, but I would [have an alcoholic beverage] every once in a while on vacation. In terms of food, I don’t know, maybe a nice piece of fresh fish with Brussels sprouts or asparagus – and some coconut.

King: My diet is pretty strict, so I don’t really veer too far from it, even on vacation, which is kind of boring. But if you have bone broth, that hits me hard. That is what I go for any day of the week.

Where would you like to travel to but haven’t?

Axel: I would like to go to Antarctica. I’d like to take one of those cruises through the icebergs and see the polar bears and the penguins and see the stars. . . . I know I talk about tropical a lot, but I love the cold and I think there’s something so beautiful about feeling isolated and away from humanity, so I want to experience Antarctica.

King: I need to go to Hawaii, but I really want to go to Africa. I hear Ghana is the first place I should go, so I want to go to Ghana.

Aisle or window?

Axel: I am a window person so I can sleep. I love to sleep.

King: I like the aisle so I can get up whenever I want [and] go pee whenever I want. I always feel bad asking someone to get up for me.

Favorite childhood travel memory?

Axel: I would say going to Disney World with my family. It’s just so magical. I remember going to Tomorrowland and the ExtraTERRORestrial Alien Encounter where you stay strapped in your seat and you see an alien, then they break through the glass and the lights go out and you can feel them breathing on your neck. It’s pretty awesome.

King: I remember going to Universal Studios with my family and taking pictures in front of the New York skyline and feeling like I was actually in New York. Then maybe five, six years later I worked at Universal Studios as a poncho salesman, but I soon got fired from that job.

Guilty pleasure when traveling?

Axel: I don’t know that I have any guilty pleasures when traveling. I mean, find the nearest juice bar and get juices. I don’t know if that’s a guilty pleasure. I think we sound pretty unadventurous – getting juices.

King: Or good coffee or chocolate.

Best travel tip?

Axel: I would say bring earplugs and an eye mask and some lavender oil to help you go to sleep.

King: Bring snacks – lots and lots of snacks because you run out very quickly. Also, don’t forget to pack an extra pair of underwear, because you never know.
