The Short Answer
A 4-hour private motorbike city tour typically starts around $38 solo, roughly doubling per added traveller. A private Cu Chi Tunnels tour with an English-speaking guide runs $307-343 flat for 1-2 people, considerably more than the shared/group version ($30 per person) because of the guide's language skill and the private vehicle. A private Mekong Delta day trip (cycling, kayaking, Cu Chi combined) runs $222-258 flat for 1-2 people. A multi-day private Mekong journey (4-day sampan) runs $3,623 flat for 1-2 people, a genuinely different, longer product.
