Do them all — you won't regret it. We've checked, and none of these sixteen optionals clash with one another. They fall on different days and different times right across the tour, which means there's genuinely nothing stopping you from saying yes to every single one. We live once, and if we deprive ourselves of experiences along the way, there's not much left to the story of our life. Better to have done it than to spend the rest of the tour wishing you had.

Ready to book? Just let Carmela know which ones you'd like — early booking is recommended, as several of these genuinely sell out. There's no wrong choice here, only the ones you wish you'd said yes to.
