I have never been to Texel before, and I have to say its well worth a try. We stayed at the Tatenhove over a long weekend. The rooms were very clean, I would certainly vote for going half board again as the food was top quality, and of a good variety (set menu). We went with the Romantic package and added an extra day, this was amazingly good value for money. The staff were very friendly and the hotel has a homely feel, totally relaxed. You are able to hire out bikes from the hotel, which we did for one day and wore ourselves out riding along the coastal paths to the lighthouse stopping for lunch in one of the villages, and then on to the ice cream factory (my favourite). There is a riding school nearby and a short 1 hour trek through the woods cost us about 13 euros.
I would definatley go back again, and totally recommend it to other travellers. The only critisism I would say is that the rooms are clean but are a little tired (we had two singles pushed together which was interesting and did raise a few giggles). But in compensation we were informed that the hotel would be closing over the winter (2009) for total refurbishment, so maybe this is going to be rectified.
