Hi stalker
We were in Las Brisas complex which is very central & we've been before so knew the area. fraid we stuck mostly to going down into town at night for dinner around 7 & coming back to villa's around 9.30/10. there was some sort of entertainment on every night. Parrot Show/Magician one night, Dancing Girls another which pleased DD(3) but not really that great. she even enjoyed the awaful singers doing bad Robbie Williams impressions.
I think all the big hotels have little discos & you can use any of them. Most of the restuarants on the front are decent. Don Camillo's is nice but very slow when they are busy & if you've impatient hungry kids it's not ideal. The Canaria Typico (think that's it) at the end of the prom going to the left away from the harbour is lovely, really nice staff & delicious food. Not very big but early'ish it's shouldn't be too bad. Chinese next door seemed very popular but we didn't try it. There's a place called Kikoland near the Playa Flamingo hotel that you can put your children into but we didn't bother DD was really happy with play area & pool on our complex. They've one of those big trampolines down on front walking towards marina. there's a place nearer the harbour end with all sorts of video games & stuff & a ride-on at every 50 yards.
Hope you have a lovely time, I'm shivering here wishing I was in sunnier climes.
