Elsa, surveying the North Mountain (and snow-covered deck).

A funny thing happens when you vacation with three girls between the ages of 3 and 6—you feel like you’ve stepped into a Disney movie. All. The. Damn. Time.

Such was life last week when we spent five days in Lake Tahoe with great family friends. The girls could see or touch snow every waking moment of every day. Which meant they convinced themselves they were living in the movie, Frozen.

This alternate reality manifest itself in a number of hilarious ways.

First, we grown-ups were subjected to the word, “Elsa” no less than 70 times every hour of every day. The girls screamed it. They sang it. They took turns being Elsa 1, Elsa 2, and Elsa 3. One morning, the three of them got into an animated conversation of what Elsa would do if she were annoyed at her sister for not including her in a game with friends. (Their answer: Elsa would freeze everyone. Of course.)

Second, every day comprised multiple costume changes. Immediately after awakening for the day (at 5 a.m.), each girl raced to the room we had designated as the play room to get first dibs on the dress of their choice. Choices included three Elsa dresses, one Anna dress and a few other non-Frozen options. Two of the three girls also had plastic, turquoise Frozen heels, which they wore at all times in the wood-floored house, thus preventing the 7-month-old baby sleeping downstairs from getting a decent nap.

(Oh, and in case you’re wondering, those dress negotiations never EVER went smoothly.)

Finally—and this was perhaps my favorite—the kids took to citing lines from Frozen, and bending those lines to fit just about every situation in which we found ourselves over the course of the trip. Whenever wind gusts took the temperature from the teens into the single digits, at least one of the kids would state, “The cold never bothered me anyway.” When L got the brilliant idea to amass snow to build a man-like sculpture, she didn’t ask her sister or friend to help, but sang, “Do you want to build a snowman?”

It’s important to note here that I am in no way complaining about this phenomenon; on the contrary, I found it fascinating and instructive and endearing (most of the time). Multifamily travel in and of itself is one thing. Apparently, multifamily travel while playing princess pretend is entirely something else.
