On the way back to California, we stopped by Madame Tussauds in Las Vegas, which we got into free because of our Legoland annual passes. Free was about what it was worth.
Aliciana and I both noticed, before mentioning it to each other, that the women wax figures were particularly unrealistic. The boys had fun but thought the figures were a little weird.
I don’t recommend paying to see Madame Tussauds. At least it gave us a break in the middle of our day of driving.
