If you are in Delhi, you can take your mum to The Claridges, and if you are in Mumbai, then a getaway to Moonstone Hammock in Karjat may be a good idea. However, if you wish to escape the heat, then a staycation at Hyatt Regency Dharamshala is the way to go. If an island vacation excites your mother, then Symphony Resorts in Andaman and Nicobar Islands. You can also take her for a staycation in Jaipur, at Fairmont Jaipur.
