Having been in the Haven OS on the Jewel and the forward-facing penthouse suite on the Pearl for a partial canal transit, I wouldn't pay the extra for the Haven on a Jewel class, even though that Haven OS was an AWESOME cabin. Like @Turtles06 said, if you get one of the forward-facing penthouse suites on deck 9 or 10 you'll get the same view of the canal as the Captain. The other thing to look at is an aft-facing penthouse suite (non-Haven). I absolutely love the aft suites, and have done that on the Pearl through the canal, too. Loved that view, too.
