Buy your DVDs online from El Corte Ingles or another spanish source. Then they will be (check of course) in both English and Spanish - sound and sub-titles. You will find the sub-titles are often an interpretation and not word for word translations. This I find really useful. I at first just watched in English with spanish sub-titles - it is amazing you can’t help but pick up odd bits (and hopefully your family will too). When I had seen the film in English one or two times I went for spanish sound, english subs .........
I also found it useful when I was rarely in Spain to set my main goal to be discovering spain, its culture, its peculiarities, its geography, its wines, its food, gambas, jamon mmmmmmmmmmm ..... Sry. and not the language. I hated languages at school so keeping it interesting was vital.
And don’t forget stick-it notes all over the house with the spanish words. Good Luck
ps someone mentioned verb tables but beware. When I was at school it was verb tables that put me off languages for 25 years. Yes verbs are important but at an early stage you can get by without endless hours of table learning.
In the UK I’m in Kingsclere, not a million miles from you, and I found hunting down spainish speakers in Basingstoke not too difficult (mostly mature students). Then I discovered that many Italian restaurants employ spaniards (cheaper) and the italian 500 yds from my house had two spaniards working there.
Sorry wittering again, good luck with your adventure
