Sorry If this question has been asked, but so far I've received conflicting answers.

We are flying from Hong Kong to Banglore on Saturday Night Aug. 15th and then on to the Maldives on Sunday Morning. As there are only about 10 hours between flights we'd like to go to a hotel to sleep. My travel agent told us that since we are going to be in Banglore for less than 24 hours we do not need a visa? Is that correct? We are US Citizens.
