Welcome, Nawlinslady! I second CR's recommendation on the Too Faced Lash Injection mascara. It takes some getting used to (at least for me), but it's one of the only mascaras that actually makes my lashes visible without a primer. Another one I recommend is Lancome's Fatale (used with a primer, for best results). It's also difficult to apply (worse than TF), but the results are amazing - especially when paired with TF pinpoint.
Speaking of lashes, I've been using the Latisse for almost 3 weeks now and my lashes are already noticeably longer. DH even noticed a difference, as well as my girls. After only 2 1/2 weeks!!!

I'm very excited to see what they will look like after a few months. Sorry, though, the pictures we took didn't work out. You can't really tell anything - nothing like the photos in the Latisse promotion. Maybe DD just needs to work on her close-up eye shots.
MPA, your trip sounds fantastic - good for you for doing something fun while your girls are away.

As far as a makeup routine for the Disney heat, I really don't do anything different other than make sure that I use primer every day. Sometimes I skip the eyeshadow primer at home because it tends to irritate/dry out my eyes, but at WDW - I use it every day. Also, the Stila Smudge pots or something similar for eyeliner. That way the only make-up I bring to the parks for touch-ups is a small container of foundation, finishing dust, and lipstick/lipgloss. This routine has always served me well in the past - no problem with make-up fading or melting off.
CR, I always, always use a matte eyeshadow. I love the shimmery look on other women, but for some reason I hate the way it looks on me.

I don't know, maybe it's because I'm too old? Or maybe my eyes are too small - I've noticed that the women it really looks good on have larger eyes.
Bella, you cracked me up with your 'hard core' makeup.
I just noticed my countdown is wrong, darn it!! We're not leaving in 7 days, we're leaving in 9 days - I must've put the wrong date in there.
