We stayed there in 2001 for our very first WDW trip and would highly recommend it. Everyone says the hotel doesn't matter that much because you spend most of your time at the parks, but at the time the kids were young (3 & 4) and you just can't be on the go from dawn until the wee hours when they're that age, so you end up spending a fair amount of time in the hotel room.
We loved the extra space, the kitchenette, the free hot breakfast buffet, the buy 1 get up to 4 "kids" meals free (we fed the entire family for $5 for lunch), and of course the pools. To top it all off, you are closer to the parks than some of the on-site hotels!
Of course this was all before the Nick renovations which sound like more kid's stuff, less free stuff, and higher rates. If you don't plan on spending your entire vacation in the parks and have a couple free days planed, it's probably worth it, even if it's your "very first" time - you'll still feel the WDW magic don't worry! If you plan all day, every day at WDW, I would think you'd be spending money on amenities that you wouldn't be using.
