Given the 10-12 hour (approximately) travel time each way by train or bus, you will likely have around 1.5 to 2 full days and parts of two other days for actual sightseeing in Gujarat. This depends heavily on your chosen itinerary and the efficiency of your travel within Gujarat. Flying can reduce travel time significantly, giving you more sightseeing hours.

Generally, traveling by train is the most economical option for the Pimpri-Chinchwad to Gujarat route. Long-distance buses can also be cost-effective but might be less comfortable for longer journeys. Flights are the fastest but typically the most expensive, especially if booked closer to the travel date. Consider checking prices for all three options based on your travel dates and booking in advance for better deals.

When visiting temples, it's customary to dress modestly, covering shoulders and knees. You may need to remove your shoes before entering the temple premises. Photography might be restricted inside some temples, so it's best to check the local guidelines. Be respectful of the religious practices and maintain a quiet demeanor. When visiting other historical or cultural sites, general respectful behavior is appreciated. Gujarati people are generally warm and hospitable.
