Maui is a great place to go with kids. Our 5 year old has been 3 times already and our 2 year old twice and there is lots to do on Maui. We usually stay in Kaanapali and love to walk on the little path there along the beach and to the different hotels and shops. Kaanapali Beach is great too for kids. You can rent lounge chairs or umbrellas on the beach too which is nice for shade for the little ones. On our last trip to Maui in March, I took the kids to the Maui Ocean Center which is an aquarium sort of close to the airport (you'll see it on your way to Lahaina from the airport). We've always wanted to go but have never gone so while my husband was golfing one day I took the kids and they loved it. That's a fun activity for the kids. We also went to Makena Beach (Big Beach) near Wailea and it is a gorgeous beach! It wasn't crowded at all and it was very relaxing. It's a bit of a drive from Lahaina - but only about a half hour or so, but it was well worth it. We liked it so much that we went there twice! Just walking around Lahaina is fun for the kids too. There's also a Sugar Cane Train near Lahaina. We've never done it, but always say we should. Have fun!
