My son is a Titanic enthusiast too,
Having a Titanic enthusiast in the family can be lots of fun. I've been adding something Titanic related to all our vacations / mini trips. We started in Orlando in March with this wonderful attraction. Next before heading to Utah National Parks (we were flying into Las Vegas), so went to see the Titanic Artifact Exhibit at the Luxor. In October we have a mini trip to Washington, D.C. and just for fun are going to see the Titanic Memorial. Then in December we're going to be in Branson, MO (very close by for us), and are going down specifially to see their Titanic Attraction -- people really like it, but say the one in Orlando is better. And then next summer, before spending a week in the Colorado Mountains (we fly into Denver), we will see the Molly Brown house which is located right in Denver.
