A clear comparison so you can spend money where it improves the trip most.

Pros: lower price, simple planning, built-in transport. Cons: fixed timing, possible shopping stops, average meals, and little flexibility when you want longer at a site or an earlier rest.
Pros: your pace, better restaurants, custom interests, easier with kids or jet lag. Cons: higher day rate. Many travelers book private only on key days to balance budget.
Use private companion days for arrival, food, and complex landmark logistics. Use independent time for simple neighborhood walks. Skip giant coach products if you hate being herded.
For flexibility and food, usually yes. For rock-bottom price, group tours can win if you accept the tradeoffs.
