Choosing day cruise or overnight cruise depends on your budget and the style of vacation you are planning. In day cruises you get to watch many activities and visit several places of interest. Overnight cruises are very romantic and you can be alone in the backwater paradise. Many houseboats allow overnight stay along with day cruise. Such boats include meals, bedroom and other amenities. However, by 5:30 pm all boats would be anchored in the backwaters for the night.
