One more thing to keep in mind that is a big reason to go for the line-of-credit plan: The actual shopping process is a *huge* part of enjoying makeup! I can't count how many times I stress-browse at Sephora during my lunch hour. I don't necessarily buy a thing, but just swatching things will make me happy. You have *no clue* how happy this plan would make your typical makeup fan. Turning us loose on many, many different lines of makeup? It's our Disneyland. And adding a hotel stay, which means ROOM AND MAID SERVICE (even if you don't order food to eat in the room, someone else will make the bed and clean the bathroom!)? That just makes it even better. And if she has a habit of picking up a little something after a hard day/week, chances are high that you will eventually hear her say that she wants something, buy it for her, and then find out that she just got it yesterday.
And then there's the part where I'll dredge up an analogy. It sounds like you were planning on personally making this, which means you are familiar with carpentry and woodworking. One of my grandfathers was a carpenter, and the other one did woodwork in his spare time, as does my dad (and he inherited my mom's dad's carpentry tools. *Multiple* lathes, bandsaws, jigsaws, and I don't even *know* what else), so I immediately thought about the fun times we've had trying to figure out what to buy them for gift-giving occasions. Imagine your girlfriend deciding that, hey, my boyfriend has been wanting a lathe, drill, and new screwdriver set! I'll just go buy one for him without checking to see exactly what he wants! Made you cringe, right? Makeup and brushes are our carpentry and woodworking equipment. This plan will land you in the Boyfriend Hall of Fame, and her girlfriends' boyfriends will probably all hate you for making them look bad. This is exactly what you want. Good call!
