Agreed. Great show. I was particularly thrilled by the motorcycle jumps!

You will get wet at some seats. It's clearly marked on the web site if you order your tickets in advance.

I personally shall not bother with a dinner/drinks/show package. However, some local H.K. travel agencies have ferry + show ticket packages that offer about 10~15% discount than buying separately. Yes, attire is casual.

I bought the cheapest ticket - Cat. C - and it was alright.
