hi, i've not been to tenerife yet but am booked for next august staying in pdla.
i have stayed in many a/i hotels in the past and can guarantee staying in one for 30 days is a bad idea as you will be sick to death of the food after 7 if not before.
when we took our 3 chidren on holiday 10/14 days, a/i was good value if you pick a good one(if you don't do your research you could end up having to eat out a lot as the a/i drinks/food can be bad).
now we only have one daughter who comes with us(others grown up) it works out no more expensive for us to go s/c, and you can see more of the place you visit plus eat what you want, where you want and when you want.
i have done some research on tenerife pdla and los cristianos and it seems cheap to eat and you can get a pint for 1euro in some places.
have a look on the forums on here and tripadvisor for which area you plan to stay in to get a idea of prices.
we went to zante last august stayed s/c and i found drinks to be expensive, food reasonable and we spent slightly less for the s/c holiday including spends than we did on our previous a/i holiday.
do your reserach and work out whats best for you
if your a couple or have 1 child i,d say s/c but if you have a big family(i'm assuming not as you want to go in jan for 30 days)i'd consider a/i
