I think the 12X12 Alaknak will get pretty small pretty quick with kids, pets, coolers, sleeping bags etc. I have the 12x20 and have taken it on several just camping trips. It really is pretty easy to set up with two adults and you have lots more space. When folded up and put away it takes less space than you might think.
The hardest part to having little ones camping was keeping them comfortable in weather extremes...cold or hot. We were pretty selective on the weather when camping with our kids when they were super young.
Is a camp trailer out of the question?
