Hard to say. Each resort has it's own perks. Read the board for awhile. Try to narrow it down and then maybe ask some specific questions. For instance, CTI is the most compact. CSA is the largest and has the best fitness facilities. CTI, CSS and CN have Au Natural areas. CSS and CTI have the Dunns River Falls excursion. ETC, ETC. I'm fairly certain that which ever resort you choose it will be fun.
As each resort has its own special uniqueness you'll need to do some research to see which fits your needs. If you were to give some idea of what you're looking for in resort those on the message board might be able to point you to the one that would be the best fit for you.
