We are planning a trip for sometime this year and are debating between May and December. Our older DD turns 5 this week so she is fine anytime. Our younger DD turns 2 at the end of May. So if we went in May, she would be almost 2 and she would be 2 years, 7 months in December. I have taken them at a variety of ages but never in the 2 year old range. Any feedback on this?
