Glad it went well. My wife's style of gaming is very different than mine (and the rest of the group, for that matter), so I'm happy whenever I can run something that crosses over enough that she can enjoy.
Also, good job on hooking the next generation of gamers.
Maybe turn this into a weekly or bi-weekly thing? Family adventure night. Sure, running for a 7 year old is going to be different than for kids your own age, but you can at least stay in practice.
