Is it safe to drink the tap water?

No. Drink only bottled water, and use it for brushing your teeth as well.

How do I handle tipping?

Tipping is expected in the tourism industry. 500-1000 INR per day for a driver is standard, depending on service.

Planning a Two-Week Trip to Rajasthan

Focus on the 'Golden Triangle' loop of Jaipur, Jodhpur, and Udaipur, adding Jaisalmer for the desert experience. Dedicate 3 days to each major city to avoid burnout, using private drivers for inter-city travel.

Map your route. Start in Delhi, head south to Jaipur (the Pink City), move west to Jodhpur (the Blue City), continue to Jaisalmer for the desert, and finish in Udaipur (the City of Lakes). Fly back to Delhi from Udaipur.
Book inter-city transit. Hire a private car and driver for the full 14 days. It costs roughly $45–$60 per day and gives you door-to-door flexibility that trains cannot match.
Schedule your sightseeing. Visit major forts and palaces early in the morning (8:00 AM) to beat the heat and the bus tours. Use your afternoons for local crafts or relaxing by your hotel pool.
Plan for travel fatigue. Rajasthan is dusty and loud. Schedule one 'rest day' halfway through the trip in Udaipur to catch up on laundry and sleep.
