I was always very sceptical about Spanish timeshares, but I can say that if you are currently thinking about buying a timeshare then I would recommend it as long as you deal with a good company.
We bought our timeshare in Marbella 4 years ago, and the best thing about it is the fact that it makes us take a full week off work, once a year, that we can spend in the sun with the kids. The rest of the year is pretty flat out with the odd long weekend taken here and there.
I will be jetting off to our timeshare tomorrow, its at the Marriot resort so its a 5 star resort and the apartment is really spacious, with everything you need on site such as 3 pools, a private beach, restaurants, bars and a shop. Hopefully this year Becky has arranged a better hire car than last year as we tend to drive out to some place or another each day with the help of the European TomTom.
So from tomorow I will be soaking up the sun, sea and sangria in Marbella, getting some much needed rest and recouperation with Becky and the kids.
