Hi shwetasngh, welcome to MySwissAlps!
Two 3-day Swiss Travel Passes for you and your husband would work fine (assuming you travel to Zurich on the 12th). If your son is younger than 16 he can travel along for free. The pass covers the leg Basel - Lucerne for free, so you only need a ticket from Paris to Basel. All further trains, boats and buses are free as well, except for the leg Grindelwald - Jungfraujoch. You will get a 25% discount there. The Titlis cable car is discounted by 50%. As you are from India you can get the pass here, as well as the ticket to Paris. For further purchase options, please see the Price section of the Swiss Travel Pass page.
An alternative is the Swiss Half Fare Card. You could do the math to see if that works out cheaper for you.
Recommended hotels in Interlaken are listed here. Hotels near the airport in Zurich are listed here.
Have a great time!
