Hey Tanya
I've been to Europe in December 2016. If you're planning to visit Europe, then you must kick start it from Paris. Paris gives you the best of all Christmas feels. It's a treat to watch Paris during Christmas and New Year. Paris can easily gets covered within 2-3 days with connectivity at its best.
If you wanna cover the maximum of European countries you should opt either for Train and Bus as a mode of commodity. Euro rail usually offers a month pass costing somewhere around 100 Euros that covers entire Europe and saves time too. While, a bus travel would cost b/w 16-30 Euros for a single sided trip, but usually takes 10-15 hours.
Netherlands, Belgium, Germany and Spain can easily be covered via Buses from Paris.
In budget of Rs 1 Lac Spain is a very good option . There are many cities in Spain which are too good and should be visited . IN fact you can do 10 days Spain in 1 lakh budget
