Last year we skipped going up the tower due to length of the queues and my impatience. This year I am pre purchasing tickets online but I have a question that I can't seem to find an answer to. If you purchase tickets for the top level does that give you access to the other levels? I'm told the views from the second are superb so we would like to go there also, anybody know? Also we are thinking early evening views would be nice as opposed to daytime, suggestions?
