If you don't want to drive the Rose & Thistle in the village does reasonably priced food & a childrens menu
In San Javier the wok buffet is really cheap & there are lots of restaurants in the square in Los Alcazares which anyone on site would be able to direct to you.
I think the swimming pool is now closed. We have friends going over next week & they have said the forecast is rain, rain & more rain so make sure you take macs etc
Have a good time
