I'm thinking that it might be fun to take the ferry on the trip back or is it not worth the hassle?
The ferry is fun, Laural. However if you are planning on using it one way then go down to PoS with the wind from astern rather than back to Scarborough as the return crossing can
sometimes be lively.
It also depends on where you want to go to in Trinidad. The airport is away from Port of Spain, so if that is your main destination use the ferry. The ferry is extremely good value for
money and nowadays doesn't take long either.
To a lesser extent it also depends upon where you are staying in Tobago. If you are right near Crown Point then fly.
Let us know how you get on if you go to Trinidad. Too many tourists are frightened to give it a try.
