You can still fit a lot in without running all over like you are. It's not all that far, its could be more efficient making more use of your time spent at destinations rather then getting there.

As far as not staying in a marina, contact Nick - you'll see that it is WELL worth staying on the dock at Leverick. You get 2 bags of ice and water too. And the discount makes it very worthwhile, even more so being on a power cat where you'd pay for the fuel the genset would use at night (assuming you use it). I think your crew will find that not having to dinghy in and just coming and going as they please a nice change. Rental car is under $100 for 24 hours. That's why we tend to stay 2 nights - pick up the rental car 4pm day of arrival, go out to dinner and 2nd night we try to plan on being Friday and do the BBQ.

White Bay is a favorite of many. We like it, but I wouldn't spend a whole day there - it gets too busy for my taste and there are other great places to visit.

We've been over a dozen times and haven't seen everything yet so just adjust your thinking and realize you aren't going to do everything.
