Wow - a little snippy, no? I mean - give the poor OP a break. All she asked for was a vote on which ADR to cancel.
My opinion would be to cancel RFC. I don't think of it as a Disney experience and their food does not justify their price. For audio animatronic animals during my meal, I'd grab a Dole Whip and go on the Jungle Cruise!
I do not think you have too many ADRs. I think you should have as many as you want, and feel free to eat every single one of them. DW & I also travel to the World without kids and the eating experiences are very much a part of our trip. We will sometimes just split a meal or grab apps and desserts just so we can experience a new restaurant or return to one of our favorites. I say make as many ADRs as you want - just be kind and cancel those that you are not going to keep, even if it is calling and cancelling the day of the ADR.
Oh, and finally - if you are doing 12 days and eating at that many restaurants, you may want to consider one AP for your party. Depending on where you are staying you may get a hotel discount, take care of your park needs, get dining discounts (especially with the DDE), and give yourself a reason to return within 12 months. A no lose situation!!!
Good luck with your trip (and some of these posts!!)!
