The survey was conducted by Phocuswright study, which is co-commissioned by ixigo, a travel marketplace. Over 2,700 travellers took the online survey.
Almost half (48 per cent) of the respondents were millennials.
It suggested that as many as 22 per cent seniors, aged over 55, spent over Rs 6,000 per night for their most significant trip during the year whereas 34 per cent of the millennials, specifically in the age group of 25-30 years, spent this much or more.
One out of every two millennial considers non-hotel lodging options such as private homes, bungalows, homestays or service apartments in preference to hotels.
On the other hand, 70 per cent of seniors tend to prefer hotels over non-hotel accommodations.
"Millennials are changing the way Indians travel. Travel apps, coupled with rising smartphone penetration, has brought about a marked evolution in traveller's behaviour. In 2017, Indian travellers on an average spent Rs 1.5 lakh on their travel and took three leisure trips across the year," Aloke Bajpai, ixigo CEO and Co-founder, said in a statement.
