You get more space. Instead of spending your vacation cooped up inside a hotel room - which is, really, just a bedroom and a bathroom - give yourself more space to relax with a whole apartment or vacation home. Your whole family can fit comfortably in one vacation rental, so you do not have to book several hotel rooms to accommodate everyone. Some vacation rentals come with private space outdoors as well, like swimming pools or hot tubs, which add to your living area and make the whole experience that much nicer than hanging out in the hotel lounge.
You get more amenities. Some hotels offer nice amenities (which you will pay dearly for), but none of them can compete with the kinds of perks you will find in many vacation rentals. From balconies, barbecues and swimming pools to private kitchens, in-home laundry facilities and home entertainment centers. Plus, some vacation rentals even come with access to things like nearby tennis courts or golf courses, too. You just cannot beat the amenities in a vacation rental.
You satisfy your whole travel group. Maybe the kids are picky eaters, and you want your own kitchen to be able to feed them what you know they will like. Maybe the husband wants to be able to catch the big game on a big-screen TV. Maybe the wife wants to be able to walk to the tennis courts every morning. Maybe the teenagers will simply die if they do not have access to the internet while they are away from home. Whatever the people in your travel group need, there is a vacation rental that will satisfy everyone. No hotel can compete with that.
