We ended up canceling our cruise for November. I was having a hard time getting an appointment for our passports on a day we could do it and now I feel like it's cutting it too close. I'm just not comfortable doing it with just birth certificates with the kids. The last thing I need is a kiddo getting horribly sick or hurt and needing a hospital and being trapped in another country with no passport. I know it's probably worrying for nothing, but it's fine. We're going to spend the week at Great Wolf Lodge in Houston and just explore the area and do NASA and the zoo and museums!
