We've been AI about 9 times now. We make AI our Summer holiday and either go S/C or H/B for Xmas.
Through our experience, we wouldn't ever go AI to any of the Spanish places again, this is where we found poor food/drink etc. We pay a lot for our holiday in the Summer and wouldn't think that we're saving money by going AI. We will only book 4 or 5*, and do lots of research beforehand.
We don't have children, but for us we find 2 weeks being waited on hand and foot is just what we need by the time we get to August!
