There was me and another guy turned up, so it was nice to have just the two of us. The tour guide was very informative and I asked her lots of questions, not just about the tour but of Malta! She was really nice and could answer all the questions.
For the price, I think it was worth it. I got picked up from Sliema and we visited the places. You get to see that part of Malta, and even driving there is nice because you can look down the narrow winding streets of that area. The museum at the end isn't outstanding, quite small, but it's okay for a Maritime museum. Though, if you get bored with the museum at the end, you can go for a wander and meet back for the pick up and nearby there are lots of amazing boats docked up and just the area is nice to look at.
Overall, I'd recommend it, especially for the price of what could be a meal out in Malta.
