the balcony size depends on the type of room you have.
we get a one bedroomed apartment for 4 (two adults - two kids) the apartment is plenty big enough and the balconey is quite big - big enough for 4 chairs and more
the two person rooms are quite small just two single beds and a bathroom (a bed sit basically) and the balconey wont fit two chairs.
you are going to a hotel rather than an apartment and there are no kitchen facilities in any of the rooms, if you want a drink in the room take your own kettle, you can get tea bags, coffee or hot chocolate from the restuarant, assuming you are going all inclusive and the retuarant are happy to lend you a couple of cups
if you are going all inclusive the food is good but watch the snack bar because not everything is all inclusive eg at the snack bar you have to pay for the bacon, eggs and chips but you can get egg and chips and a bacon sandwich free on the ai basis and the same goes for some of the drinks eg if you want a sangria with triple sec you have to pay, but if you get a sangria and a triple sec as two seperate dinks thet are free, but if you study the menus you can work out a way round having to pay
the barcelo is a fantasic hotel in a fantastic resort you will not want to come home
