You should know what you can expect here. You can learn everything you know about the universe and the solar system here. You can stay here all day, and then still be very interested in what they offer, or you can just spend two hours walking around here. The length of the visit depends entirely on your (your child) interest point. The ticket fee is a bit difficult to understand. There are some very nice shows but you need to pay extra. Although this is a bit strange, you can only book two shows at the beginning and then go back to the counter to book the next one (after you have watched the first scheduled show).Be prepared to queue up for tickets, especially when children are on holiday. If you know what you want to see here, I recommend buying tickets online. The scenery outside the planetarium is also beautiful. Please also arrange time to play outside the planetarium.
