We stayed on site yes, ours was Sanguli, Costa Dorada.
Do you have a brochure ?? In there it will show which parks do transfers. I don't think it says on the site, not sure.
We went in early Sept and the weather was lovely. It was always warm enough to walk round in t'shirts/shorts etc and go in the sea/pools. A couple of the days were baking hot.
We hadn't expected there to be any entertainment or anything on when we went as it was out of seasons but there was something every night. It was mostly mini discos and things for the kids, but they also did a production of CATS one night which was fab. There was also a kids club but we didn't use it. On the site we went to the entertainment is held in a huge ampitheatre which is brilliant.
We used the pools alot and the beach which was over the road from the complex. We also took the bus into Salou and went round the shops, and for a day out we went to portaventura theme park.
Err what else ? Oh taxi, i think was about 30 euros from airport to site. Not cheap considering how close we were tbh.
Oh eating out. On our site, there was a resturant and a take-away. We didn't use the resturant as we found one right on the beach that we liked which was cheaper.
We did use the take-away one night and that was fine, we just had pizza and chips.
I have never been to any of their other sites but we had a fab time and have recomended it to alot of people and can't wait to go again.
