First, i took a flight to Bangkok from Mumbai and then Phuket from Bangkok. Visa on arrival at Bangkok airport. Cost of flight around 22000 INR. Reached airport at 10 am. People insist to buy sim card, currency exchange. But remember it is much cheaper at outside of airport.
My hotel is at Patong beach. So there were many options to reach at hotel. I prefered mini coach (12 seats) beacuase it was cheaper than taxi. Cost of taxi is 2400 INR and in mini coach is only 400 rs.
When you are travelling at Patong, drivers of coach and taxi will stop at one shop where booking of day trips are available. Please do not book with them, because you will find same trips at Patong in almost half prices.
My hotel name was "Boomerang INN". Booked via booking.com in 4300 INR for 5 days. It is located in Patong and 2 mins walk far from beach. Hotel is at very good in location, AC working well and clean rooms.
