We are a family of four with two boys ages 6 and 11. We are planning on getting a cab to Magazine Beach / Aquarium Restaurant for our day in port. From what I've read this beach looks great, isn't crowded and we won't be hassled by a lot of vendors.

I like to have a backup plan when we do stuff on our own just in case we encounter difficulties with weather / cab drivers / etc.

We're doing a more comprehensive tour in Dominica the day before, so looking for something low-key hence the beach.

Any suggestions?
