It depends on your level of quality I suppose.
We stayed at Pirates Village, Santa Ponsa Majorca last October. The hotel is really fun, all piratey and cool for the kids. The pool area is great but we found it cold in Oct (the weather hadn't been great). The staff were great, the room was fine (1 separate bedroom, living/kitchen area), the entertainment was very good and well attended as were the kids club although we used neither. On a Sunday and Thursday afternoon all the staff dress as pirates (v. impressive) and have a fight around the pool, then involve the parents and golden coins in the pool and jumping off the top level of the tower- it's really great. There is fake grass around the pool which is actually great as it's non slip and very nice to look at! We found the food a bit samey, every day there were ordinary things like chicken nuggets and waffles for the kids, plus a good selection over about 4 buffet tables- pasta, salad, bread, one item freshly cooked to order every night, soup, meats, veggies, there was everything really. All drinks too. Depends how fussy you are, we ate out 2 nights of our 7 days just for something really lovely.
We liked it, for the kids, it was a different hotel than the norm. The cold pool was a disappointment as I would have liked to have wallowed in and out but dh and the kids were jumping in- I am a bit pathetic. We like to go somewhere different every year, otherwise we would consider it again.
Our kids were 2, 7 & 10 at the time, and as you have lots of kids I would recommend it.
