hi meanabelle,
first of all many CONGRATS!! I also responded to SAIC's BFA as prior degree student - but I don't think I am going to go regardless their offer, I really like calarts and I was on campus to interview. I like the current students and faculty - so I think I am more inclined to go to calarts. I haven't heard back about financial aid though. I would say, that you should definitely attend the school that you want to especially if it's your dream school! I think that an opportunity like that might not come by again and money can always be earned back. but it's your choice and I wish you all the best, RIT is a great school!
