The Value Resorts are all my least favorites. I think Disney could have done better than standard motel squares with giant things stuck to them. And, for the price you pay, you deserve getting more than a pool and a teeny tiny room with only one sink. Your standard hotels give you more and at a cheaper price. At the Values, you get extremely minimal services and amenities, just pay extra for the Disney name. You belong getting a slide, a family restaurant, recreation, a slightly larger room, and double sinks.
But, yes, I would stay at a Value if that were my only option before going off-site.
I do not, however, think that I would ever stay at Coronado b/c of the bad stories I have heard about that place, especially the food court "tippages" and specific layout for conventioneers. And the West theme is DEF. not for me! Ahh, oh well.
