Display / Check in and Check out

I’ve got 2 issues with the plug in.

1. Display
When I put the shortcode [hotel_list_all_room], The images of the rooms are not aligned in the page. Also, in responsive mode I want only 1 photo above the others.

2. Check in / Check out search
To have a search result, I have to enter a price but I want to put 0$ because the price is fixed with the additional services selection. This is why I’ve got no result… Is it possible to show a result by adding 0$ to the price of my room? I try but its not working.

Thanks for your help
