"Saying yes to Bryan, 31, was the best thing I've ever done, and I'm so excited to be his wife," Hampton tells PEOPLE of her June 25 wedding in Los Angeles.
Guests dined on tacos – the same food the couple shared on their first date – and drank li-hing moi (Hawaiian) margaritas to pay homage to Bryan's home state of Hawaii at their seaside ceremony.
They also opted for a cupcake tower, plus waffle and s'more bars in lieu of a traditional wedding cake.
For their big entrance into the reception, "Thunderstruck" by AC/DC played on the speakers, but the bride and groom slowed it down for their first dance to "Thinking Out Loud" by Ed Sheeran.
"I can't wait to spend my life with this man, and I'm so excited that our journey together finally began," says Hampton, 23, who walked down the aisle in high top Converse shoes and wore baby blue nail polish as her "something blue" tradition.
But still the couple couldn't be happier.
"I'm so happy to be married to my best friend and adventure through life with him."
