London feels like a giant Disney park for adults right now. Each Olympic venue takes you on its own emotional rollercoaster – some, not for the faint-hearted.
Lucky for me there's no height restriction to get into these rides. All I need is my accreditation pass, which as a non-rights holder lets me into the media zones but does not allow me to film.
I can take pictures and tweet though, and hopefully I can convey a little of that atmosphere here for you in words.
The velodrome has been the most intense of all the venues I have visited so far.
Its 6000-seat capacity is smaller than most, so you feel closer to the action and the acoustics in there are incredible.
From the moment that final beep kick-starts the cyclists, the roar jumps straight to full volume and stays at a constant ecstatic pitch until the finish-line is crossed.
When the cyclists aren't competing, they keep themselves busy, rotating through exercise machines like a little hive of bees.
This is a pressure-cooker environment with the temperature to match. It's kept at a constant temperature of 28degC, because the warmer the air the thinner it is, and that means faster track times.
The cycling fans seem to be the loudest so far, but the equestrian spectators are by far the most knowledgeable of their sport. This is after all the home of eventing, so the fans know who to look out for.
Mark Todd is among those at the top of their list. He's riding royalty here.
In fact, when I went in to watch cross-country, there was a couple sitting behind me who was British but were there to support the New Zealand team purely because of Todd.
There was a hitch to their plan though. They had bought a flag to wave but forgot to check the difference between the New Zealand and Australian flag. When I told them their faces dropped.
"Oh no!" they said. "We think we bought the Australian one!" They pulled it out of their bag, but luckily they had indeed bought the New Zealand flag.
Also sitting in the Greenwich stadium were the royals, Prince William, Kate, Prince Harry, Beatrice, Eugenie and others. No one actually realised they were sitting there in the cheap seats along with everyone else until there was a shot of them on the big screen and a huge cheer went up.
They were back again for show-jumping the next day to cheer on their silver medal-winning cousin, Zara Phillips.
After the medal ceremony, they came to the back of the stands to ask if they could go and see her.
It was like entering a wolves’ den with all the photographers standing around, so Will quickly grabbed Kate by the hand and pulled her through. Mike Tindall also walked down through the crowd after congratulating his wife.
I also visited the aquatic centre early on in the Olympics. It's quite an amazing building with two big wings on either side to accommodate extra seating that will be dismantled after the Olympics.
It means that if you're sitting high up you can't see the people sitting on the stand opposite you because the roof dips down in the middle.
You can see the pool from up the top but it is nose-bleed material up there. You certainly wouldn't want to take a tumble down the stairs because you wouldn't stop rolling for awhile.
I'm yet to see the main stadium because it has only just opened.
It holds 80,000 people so you can imagine the park is packed when that many people are trying to get in and out. It's so busy that the mall adjacent to the park has closed its shops between 10am and 5pm because of fears of overcrowding.
It'll be worth battling through all those people to see our Kiwi athletes compete.
Battling my way through a few people will be nothing compared to the battle they will face out on the track and field.
