Hi! Sorry i have never stayed in haridwar - in rishikesh stayed at this hotel near the laxman jhula - i forgot the name tho! Sorry!

About delhi - haridwar, you are better off arranging a driver with a toyota qualis who knows the area, the streets and all the little quirks about those places - a good driver with local knowledge will definately be able to make the trip more enjoyable. Try any local TA there - normally the concierge at The Lalit does the bookings for us.
you will definately enjoy your stay there, the staff, rooms etc everything is great - ive been staying there every year for the past 5 years and even had my engagement party there in Feb. If you do stay there, go to the bar next to the lobby - even if you dont drink alcohol the guys there will really take care of you - in particular one chap named Yogesh
