Should We Start Our Travel Blog?

When we do eventually choose the holiday packages and then finalise all of our plans I think we should start up a blog and twitter account so that we can let our families know how good of a time we are having while I am away. I know that we are trying to get away from things for a while but you also know how much I love blogging and what our families will think if we are not cantactable for any period of time. They would start panicing and they will probably try to send out some sort of search party to find us if they do not hear from us every couple of days. This way though we can make updates and not even need to ring them or anything and really just think about ourselves and what we want to do for a while. What do you think?
