Hey Manoj, You can book hostels at www.hostelworld.com. Or for cheap hotels book at MMT and for nice cheap hotels book at OYO. And charges for the scooty or bike will be apprx 1k per day from Nov-Feb (Take your driving license with you). Hope this would help you.
Hi Manoj, I have attached with this comment a card for hostel in Panaji. You can find all the details if you click on it and you can use the same link to book. Also you can ask the hostel owner he will arrange the scooter booking for you.
