Then you should visit for Jaipur - Bikaner , Auli , Rishikesh, Kullu Manali , Spiti Valley, Kedarkantha Trek. All places are around nearby Delhi and not too expensive.
No preferences as long as the place is nice. The climate though should be moderate - not too cold. The place should not be more than 1000kms or traveling would take the entire time. Should not be too expensive, and should be worth it. And starting point should be Delhi
