Hi, just came across your post. I work at Shearings.

We do coach holidays to Spain and many other places across Europe. The best url for Spanish holidays is under the seharings homepage tab for "Our holidays" which highlights all our Spanish holidays. Alternatively, go to the homepage and you will see the special offers page.

Hope you have a great holiday.

another couple to look at are

Interbrava also do them but they are very selected dates and durations.

As i'm from Scotland I have only ever used Siesta or Interbrava as the others don't come north of the border.
