jammy gives some excellent advice there. :D
You'll enjoy Varadero so much more if you get off the resort and head into town.
Towel wars and lounge hogs were very evident at the Tryp, at least at the pool. We didn't have a problem getting a lounger on the beach.
there aren't any bad rooms, but the resort is divided into two areas. They tend to put the families in one section around the childrens pool and playground and all other adults around the main pool.
I'll have to look through my stuff and dig out the resort map for you.
We didn't eat at any of the al a cartes, we were more than satisfied with the buffet. But I heard from other guests that the al a cartes were fantastic and easy to book.
