I recently visited Kolkata and Digha. If need any type of help regarding hotel booking, travel cost,best places for food etc contact me I will help you at my level.
Hi, I have attached with this comment a destination guide for Kolkata which includes all the information about travelling to Kolkata, you can click on them to find more details about them.
You don't need a guide. get a hotel near park street and explore the city. ola and Uber are in abundance. no need to go for any package or tour operator.
