Our family plans to go to Aulani and I'd like to know what the weather is like during end of December or early January since that would be the time we would visit. My kids are both in college and ages 18 and 25, so what activities would you suggest for their age? I'm just trying to get an idea of what type of clothes to pack or gear to take. If you recall what room you staying in and where let us know if you really liked it and why ALSO if you didn't like it and why???
