Haven't been in decades - and will likely not return.
Knowing full well that Centre Island is geared more towards younger kids, I still dragged my 2 teens there knowing that there were some activities that they would enjoy (boat rentals, bike rentals, maze, tram, skyline ride). Boy, were we disappointed!
It all started with the boat rentals. We were looking forward to canoeing for a few hours but when we arrived at the boat rental we were told to come back after the light drizzle of rain stopped (the young staff were much to engrossed in their own conversation to even acknowledge us standing there). This was at 1pm. After walking around in the rain we came back when the skies were clear at just before 3 to be told they were closing (they actually close at 5). Then the staff left. Not impressed.
While we were there we decided to wait for the boat tour of the islands. The schedule said they gave tours until 6. We sat there for almost an hour waiting for the boat to come and it never did. The boat tours were apparently 35 minutes long.
Skyline ride - closed. Maze - no longer exists (doesn't say this on the website). Bike rentals - like the boat rentals we were ignored (there had to have been at least 5 young men there talking to each other). We waited at the booth for 5 minutes and just gave up and went home.
