The fare mostly was between 1500 to 2500 with complimentary breakfast. Normally i carry phone number of 2-3 hotels on the route i travel ranging beyond 9 hours drive, as you can't predict what distance you may do in particular day. Rest for other things where you know that you will be there that day, you need to book them through Travel Portal.
Not in this trip, but sometimes you need to pay some amount Rs.200 to Rs.500 to some hotels to block rooms for you. If you can't make it then that amount has to be forgotten. Hence, you need to keep at least spare Rs.200 to Rs.700 overall for such cases.
There is one hotel named "Foodie Woodie" some 3 kms ahead of Kalghat. There rates were on higher side due to Diwali festival (Some 3k+ per night) hence i stayed at Highway Retreat at Rs.1500 per night. Anyways, for food you can approach foodie woodie
Their site address is foodiewoodie.in
You can very well post the questions you had in mind, i will try to answer them as per my experience.
