Sorry for slow reply, didnt have internet for few days.
What ive been saying is for people to appear after 12 as its pointless before that, but as the tour starts at 2pm for those wanting to go on it you might as well as it gives you free parking then) will be there by 2pm latest obviously.
After the tour I was going to suggest moving to another part of the harbour area for an additional photoshoot or something similar prehaps depending on what the parking is like!
Feel free to contact me on the number below tonight or tomorrow.
I hope the weather is good enough for everyone to enjoy the day!!
