Vacations with toddlers can be interesting!
One of our little ones was very prone to car sickness and so we stopped a lot on the road which made for very slow trips! At least we stoppped - one friend has memories of her self and two siblings, and the family dog, all throwing up in the same bucket as dad would drive non stop to the destination!
Sharing with other families can also be tricky when you have little ones. We found that beach holidays, with friends in their own cabins nearby worked best. No getting in and out of cars, or tight schedules, just lazy days on the beach for the kids to explore and play. Each family had the freedom to come and go as they pleased which worked best. Fun games and talking nights for the adults once the little ones were down for the night are great memories. I love summer holidays!
