A Whitsunday Quandry

I manged to find the underwater housing for my digital camera on eBay - whoop! For about £50 cheaper than anywhere I could have got it over here, so that's one thing of the list.

One of the last activities I'm trying to sort out is what to do on my full day in the Whitsundays.

I am torn bwtween these 2:

Whitehaven Express - $140
Cruise to Island with walk to see lookout point onto Whitehaven Beach
Cruise to Whitehaven beach. Spend time there and have BBQ
Cruise to bay for snorkelling
Possibly some whale watching.

OR

EcoJet Safari - $299 (or possibly less if I meet up with 2 others/they have a space on a ski)
3 hour Jet ski tour around Northern bay (not near Whitehaven)
Chances to see secluded beaches, rivers, jungly stuff and ski through them.
Only 15 people tour with stops for snorkelling etc
Lunch back at the resort

Whitehaven seems to be the place to go and definitley something you want to see, however some of the reviews for other tours say stuff about rough sea and bad weather - which wouldn't really affect the jet ski but wouldn't be much fun on the boat!
Apparently the BBQ is good stuff and you definitely get to the beach.
The Jet ski is expensive too - although if I do manage to share a ski that would be better - but maybe then I wouldn't get to drive it.
I really like the idea of the excitement and adventure of the jet ski, getting closer to the nature, and seeing places people usually don't see.

Hmmmmm......
