You will find all budget stays.. ranging from hostels to heritage rersorts.. getting around is easy if you haggle with the autowalas, the tourist places dont charge a lot... so more or less the b udget can be determined by the kind of place you stay at

Totally depends on you buddy , if you want to have a royal feeling or just want to stay low on budget. You can find both the options in Udaipur. Choose accordingly and enjoy 🤟😎
