We're leaving this Saturday (hooray!) for our first time at CN. I've found the answers to most of my questions by checking out the message boards here - I'm only left with a couple things I'm still not sure about.

1) How much cash should we consider taking? This would be for tips (i.e. shuttle driver, cat cruise, etc) and any odds and ends (shopping excursion, some rum and coffee to bring back). I prefer not to carry more cash than necessary - any recommendations?

2) How far in advance do we need to book a couples massage? Are there same-day spots open, or should we head to the spa desk early on?

Thanks in advance for all your help!
