I went to Galveston, TX. My first time there. We went to Moody Gardens and stayed at the Moody Gardens Hotel. The beach was still recovering form the hurricane. The waves were strong. The town seemed like a small one, nothing really exciting. But the area around Moody Gardens was cool. I did a lot of swimming and water parks. Got a great room for $299/night with a free upgrade.
My favorite spot to vacation would be almost anywhere in Florida.
I spend most of my vacations in GA though. Spending time with my family is relaxing to me.
