Small group tours (max 15 guests with us) are the best value: door-to-door hotel pickup, a professional guide, and shared transportation that keeps costs reasonable. You meet other travellers, you follow a polished itinerary, and you are back at your hotel by dinner.
Private tours win when timing, mobility, or interest matters. Travelling with grandparents who need extra time at each stop? Want to skip the winery and add a second viewpoint? On a tight cruise-ship window? Private gives you the flexibility to rewrite the day on the fly.
The other quiet advantage of private: the vehicle is yours. You can stash bags, change layers, and leave purchases in the SUV instead of carrying them. For couples celebrating an anniversary, the private upgrade is almost always worth it.
