You can pre-book your English language tour online. This has been an issue for me and several others so I want to share the info with you all. Send an email to:
and request the day/s you are interested in. They did not give me a list of times but did offer a time based on my requirements, which was fine. The cost was euro9 per person plus a euro1 booking fee. The response time was 24hours and I experienced very professional and helpful service. For some reason it did not work on my first request but when I sent my request the other night I received an immediate reply. But all is good now. Hope this helps future visitors.
