NESurf,

We have never prepaid, so can’t answer about the mentality of loading the ferry. I have never seen anyone turned away because the ferry was full. The logic to not prepay has more to do with you really don’t know timing and which ferry company you will be using.

Re taxis: there is an individual at the taxi stand who will direct you which taxi to get in based on where you are bing dropped. Not really an option to get in any taxi that looks almost full.

Enjoy your time in the islands!
