is it allowed for an unmarried couple to stay in an hotel room?

Yes, you're very right. Sorry.

My "daughter" (former fellow uni student) and I had to share a room for a few nights when travelling India last year for a couple of months. We had no problems in booking, despite (or because of) some managements' obvious problems in deciding to regard us as a married couple or father-daughter. (I'm now 65, she's 27.) Stays were of 2-3 days or more, so that might have been reassuring, and we're both Swedish citizens.

if its a small town and you dont look like married couple, its better to stay away from hotels. police in small towns (specially not tourist spots) can be nasty on young couples. they are usually after money and will try to create big issue just to get some money from you. and if you fall into their trap, it may not even be safe for you and your GF.
they usually harass with the threat of calling your parents and letting them know about your affair and stories like they found you in objectionable condition.

if its a popular weekend outing from your town and lots of young couples visit that place, you should be safe. but if the town is not used to merto lifestyle, you may avoid it.

thanks Nomad,that information was of some help. i will definitely consider the point you said.
but the place is like a pilgrim, you know, mayapur is the headquarters of ISKON. therefore it is quite often visited by the city people...so in that case i guess it will be safe...what do you say?

I'm from kolkata and I visited Iskon with my family last year. If you are staying in the grounds of iskon like we did you will enjoy your stay. They keep the place neat, well maintained and without a doubt its safe. That implies no problems with cops, stupid ppl trying to take advantage etc. In the evenings you can visit the temple or relax by the fountains. Its a wonderful place though not particularly romantic. Iskon has a lot of guesthouses which are well maintained so booking a room should not be a problem. The rooms though clean are however basic, clean white sheets, blankets, running water , ac rooms available etc. I suggest you search for iskon's number in the net and directly call them and enquire about rates, availability as well as any reservations against unmarried couples. That way you can put all your doubts to rest.
Regarding other hotels in mayapur I have no idea, besides those will be in crowded market areas so its best to stay in Iskon itself for a nice stay. Mayapur has a lot of foreigners residing and visiting so its comparatively open. Even places near raichak like omar resorts and palm village refused us entry since we are not married. However places like gangtok darjeeling but not siliguri are very open and we enjoyed wonderful holidays there. They are a little crowded so lava and lolegaon which are 2 or 3 hours from siliguri are perfect for honeymoon type holidays. The hotels can be booked as you reach siliguri through the travel agent counters there. That way you can have totally private, romantic, safe and peaceful holiday. Hope that helped and For more info let me know.

police tries to gain advantages sometimes if they find a good innocent couple. me and my girlfriend were roaming around victoria grounds and suddenly a cop comes behaving as if we have committed something wrong... me too planning of a day's trip to mayapur or diamond harbour but literally worried of these nuisances.... when the government is allowing live-ins then whats the issue with roaming together or lodging in a hotel....

Hi
Do not say to the Manager at the hotel, that you are unmarried and you have come with your girlfriend.

Thanks

I did not get you, i mean are you also a victim of these issues, what you do in such a situation ? @ alokcliks

Hi Deadman
Whenever I go and stay in a hotel with my wife, hotel manager never ask for any proof showing that she is my wife

Thanks
Alok

It must be that hen-pecked look on your face!
