I have been ok on smaller ships (Regent/Silversea) with my ginger capsules but I am concerned about the Silver Origin and the Zodiac boats. Am I likely to be sick; if so, I don't want to go. Additionally there is a Tauck waiver which talks about snake bites, drowning, hiking over uneven rocks and falling, etc. When I went to Ankor Wat and Mont St Michel, they definitely exaggerated the dangers. Would like to hear from real people who have gone. We will be 70 on the trip and are active but we are not 20. Are the excursions generally early, e.g.8 AM?
