A great park and keeps improving the existing, plus building new rides. Clean it is, and fun it is for every generation. It could be very busy but the park is spacious and never gives a cramped feeling apart from the queues.
For weekends: go on a cloudy but mild day in March before Easter. There might be some maintenance (which is good!) but then you can do everything you want in a single day, plus the cold-prone coasters are open on mild days.
