Lanzarote is nice. I'm going there in January and it'll be around 21 degrees. The flight is only 4 hours, 3 depending on what the wind is like, and I'm pretty sure that there isn't any time difference. It's not a massive place so 1 week is enough to be able to see all of the sights, although I'd suggest 2 weeks if you want to go there for sights and a relaxation period.
