So you went to the Observation Tower as well, and so soon after it opened! I went on Monday after HF finished, and was so pleased I stumbled across it, so worth going despite me not liking heights.
It's a pity you couldn't make the boat trip, didn't get round to say good bye to you. Till next time!
Maybe too soon as toilet door was still locked when I was there. Were you be able to enter the toilets when you were there on Monday?
