Be aware that there is limited seating indoors, basically 4 benches. Top deck is fine, but no shade. If you are like me (redhead, blue eyed, fair skin) you need to stay out of the sun, so you will be standing for most of the tour. Tour narration incomprehensible, couldn’t really make out most of the what the guide was saying. I should have researched better, find a tour that has more indoor seating. It would be a fine cruise if I weren’t so sun sensitive. Not the tour operators fault.
