How to implement a booking system using Drupal Commerce for checkout? I have been playing with Rooms, Availability Calendars, commerce availability, and many other modules to achieve my goal but I have had no luck in trying to achieve exactly what I want to do. 

Does anyone know of the best solution to achieve the following:


A holiday home booking system where users can search node teasers via available dates and checkout via Drupal Commerce.
Views integration: Search nodes on available dates
Checkout: be able to choose a date range from available dates and checkout through Drupal Commerce.
You should look at the Easy Booking distribution, to check if there is anything in it similar to what you're looking for (specific to the way this distribution uses Rooms and Drupal Commerce). If you find something, it is just a matter of reusing what's appropriate in your own site, or just use that distribution (attention: it only has a beta release so far).

Here are some more details about this distribution (quotes from its project page):


  ... to set up a website, that will suit all your needs in managing your own hotel, inn or hostel online.
  
  It gives a set of options for visitors to make room reservations, contact hotel administration or just follow hotel’s newsletter to be aware of all special offers and discounts.
  Easy booking profile is powered by Drupal Rooms and Drupal Commerce - widely used and popular contributed decisions, which means active maintaining and timely technical support.


Note: for some other module suggestions that might possibly help, refer to my answer to the question "https://drupal.stackexchange.com/questions/173341/how-to-create-this-reservation-form-in-drupal/173467#173467".
