We were there in November. My husband works for the Army Corps of Engineers, he was sent out for a few weeks to help FEMA. He felt bad about being gone over Thanksgiving, so the family travelled to him--less my older son, who had work and school and didn't want to miss.
Most of Maui is great! Only DH went into Lahaina and surrounding areas--he got to see the Banyan tree and all the wreckage. They are trying to rebuild as fast as possible, while respecting the artifacts and culture of the area. I know the FEMA workers were very excited that the new elementary school is scheduled to open up this month--children are literally having classes on the beach, and this is an important symbol of restoration to everyone.
As far as regular tourism goes--the people of Maui were so gracious and so grateful, I can't say enough good things about them. We were in Kihue, DH couldn't pay to get arrested--he got so many perks and discounts, he was embarrassed to mention he was working on the restoration (he was frequently asked, "What brings you to Maui?").
We (the kids and I) mostly stayed in the Kihue area. The kids went snorkeling, had a spa day/cabana at the Fairmont, we went to the Whale Sanctuary, and hung out by the pool. We didn't get much time with DH--he was working 12-hour days, 7 days a week, but they gave him part of one day off. We went to Monkeypod Kitchen for lunch, and one evening, he went to the Maui Brewing Company with DD28. We had a really nice time, although it wasn't a fancy type vacation for us.
DH signed up to do another tour this spring--if he's called, he won't have much notice. If he happens to go in June, the family will visit him again, this time with DS26,the one who stayed home. We'd love to go back! It just really depends on the kids' schedules if we'll all make it. My youngest (turned 18 today!) even said that, if Dad needs to be there and miss his HS graduation, he's okay with that--the kids appreciate the work their dad is doing there.
If you have specific questions, I'd be happy to answer them if I can.
