I'll go too! Looks great! And with a free airplane ticket, I'll even pay for the rest... 
What you call "the rest" may be a considerable amount of money. Yes, Euronat is expensive. If you're not into camping, the cheapest accomodation is a so-called "Studio" of 290 sq.ft. that is supposed to sleep three and costs a whopping 567 Euros (approx. US-$835) per week in Summer. Even for a simple tent pitch without electricity, you will be charged 224 Euros (approx. US-$ 330) per week!
That taken aside, it is a great place! We have spent a wonderful and most relaxing holiday at Euronat, and the photos Delphina has posted bring back pleasant memories of all the things I've done at the resort: swimming in the ocean as well as in the outdoor and the heated indoor pool, taking long walks at the beach, bicycling, jogging, playing table tennis, going shopping, having lunch at an open-air restaurant, queueing up at the bakery every morning to get our breakfast baguette, socializing with other holiday-makers and generally having a good time - enjoying all this in the nude! Sounds like fun? It sure was! But now we need to save some money before we can afford to go there again...
