As luck has it, the former is coming up in Auckland in a couple of weeks and we are going to make the pilgrimage one way or another. I'm not sure how the children will handle traipsing in and out of displays and vehicles but hopefully we can keep them somewhat happy in the knowledge that we are doing it for a purpose that will benefit them too (otherwise perhaps nanna and poppa will oblige childcare for an hour or so especially while baby sleeps).
Realistically we'll need to get adult multi-day passes, to do justice to the process of researching and exploring but we may as well spend the time and money while we have the opportunity to see 'everything' in one place.
What I hope we will come away with is knowing which living and travelling solution would suit us, and if a vehicle really does exist for 7 full-timers (with permanent beds?). At the very least it will be fuel for our dreams, and another step in the right direction.
What is your 'next step' in the direction of your dream ?
