I applied for a college intern program and was accepted but ended up not going as I would have had to prolong my college career an extra semester and was not ready to do that. They were only offering in the area of min. wage. I don't know what program she might be doing, but with mine they gave you about 40 hrs per week and then I would have been living on the property in special apartments they have set up for interns. They made you pay rent for these at something like $70 per week which sucked up a lot of your earnings. All in all, she may get rich in the sense of fun and magic she will experience and bestow upon the lives of others, but in a monetary sense I don't see it happening...lol...I'm sure she will have fun nonetheless.
Also, has she been cleared to do an exciting job like costume character???? The pay is the same but it is more of a big deal as usually people who go there to work end up doing something like food services or park greeter. Hopefully she get the position she is anticipating...
