If I was you I would try and stay in the Residence rather than the village. Its just a short hop over a bridge to all the action in the village rather than a mile long one from a room in the village. If you stay in the residence you are right near to the baby centre etc.
The baby centre was excellent, has soft toy area where baby can stay all day if you want as staff seem excellent and it was somewhere where they can be out of the heat. There is a kitchen full of milk, for free, sterilisers and microwave.
There is a mini fridge in the room which you can clear out and fill with what you want.
Take your own inflatables if you can...they are 20 euros plus in the shop on site and even in town are over a tenner and on to that you have to add the cab fare of 15 euros.
But it is worth making a big shop as soon as you get there for kids stuff, like crisps, sweets, drinks etc. because it costs you ridiculous amounts in the shop on site...eg 3 euros for packet of crisps, 2 euros for a lollipop etc. You will save a fortune doing that at the beginning. you aren't supposed to, but I did fill her bottle with juice at dinner times etc but if staff catch you they do tell you off. Better to get a bottle of squash from town and keep with you.
At kiddie centre there is a box with buckets, spades etc. you can borrow and return. The kiddie club for our three year old was excellent, well supervised and tons for her to do.
The washing area in village consists of only two machines, the older looking one was better, the other one took well over two and half hours to wash things. They are free. There are driers but the whole laundry room is often busy as obviously two washers for over 2,ooo people isn't adequate.
Take your own washing powder, its fortunes in the shop.
I don't know what the cots were like as she didn't use one. The buggies they hire out looked good though.
the mossies weren't too bad when we were there in june. The best block for not walking would be right by the centre as everything sort of goes on there but then you might get noise at night.
We were in the furthest block from centre and I got really fed up pushing her four,five times a day to and from so can't imagine what it would be like for you having so many little ones.
The residence looked better bet to me, all the rooms are accesible by lifts, no walking up hills and you just cross the bridge to get to all the action of the village.ps don't rely on shop in hotel for nappies, wipes etc. they wanted 15 euros for a plastic babies bottle and about 20 plus for nappies!!
