A really good value 3 day pass, much cheaper than the other companies and just as good.
Our guide Lee was very knowledgable and keen that everybody enjoyed themselves and answered all questions asked. He pointed out all the points of interest and explained the best stop to get off for various places etc.
The agent based at Central Park was brilliant when we redeemed our voucher, he split each set of vouchers up, explained what they all were and told us what pass included and what routes we could take, he couldn't of been more helpful.
Not rated as highly as the red bus tour. Bus stops not marked clearly.
Tour guides and routes could be better.
The bus tours were a good experience, although a bit confusion due to stop shifting/displacement/skip...
Changing the voucher into tickets at the street agents was apperently highly complicated. To be improved.
