You are right Coleman! La Sagrada Familia was design Antoni Gaudí, a Catalan architect who worked on this project for almost 40 years until his death in 1926. It is the major tourist attraction in this country.
The Costa del Sol has a lot to offer, one of the best venues for honeymoon is Hotel Tamisa Golf.

Presuming you wont want non stop clubs/pubs like Magaluf then Alcudia/PlayaDeMuro/Can Picafort ar all great, If you want a lot of clubs etc but not as much as Magaluf then Salou is probably the best, Good Luck
La Sagrada Familia should be the place to go to. It is a large Roman Catholic Church located in Barcelona. When completed, the highest tower would be more than half as high as those that stand today.
I just spent a month in Alicante, Spain. It was a beautiful city located right on the coast. It has some really stunning beaches along with awesome people, food, architecture, etc. I wouldn't trade my time there for anything. It seems as if it commonly gets lost in the hubbub of Madrid and Barcelona, which is stupid considering how unique and pretty it was. I'd definitely recommend it if you'd prefer to stay away from some of Spain's more touristy places.
La Manga del Mar Menor:

-Good food
-Quiet
-TWO SEAS

Weres the bestest place to go in Spain for a honeymoon
