Great TR, Marnie! We did DLR for the first time last September (Labor Day weekend), and the crowds were surprisingly low, which made for a very pleasant experience. We also like Space Mountain much better at DL!
We also went to Vegas (on a separate trip) last September for a friend's 40th birthday. What you wrote in your conclusion about how spread out things are on the Strip is absolutely right. We were staying at the Bellagio and had dinner reservations one night at Il Mulino in Caesar's Palace -- right next door. But it STILL took us more than 30 minutes to walk there and we were late for our reservation! The hostess said that happens a lot! Everything looks so close, but it's really just not!
Legoland looks like a blast. We're going to have to get the kids there soon. Everything I've heard from folks who have done it is the same as what you said -- it's really best for kids under 12.
Thanks for sharing all your wonderful photos!
