Biggest opportunity: Swap “appointment booking” for “boat rental”. “appointment booking” isn't earning its slot: it only gets you to #12. “boat rental” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →0.7%
of downloads still active
At least 40K of 5.4M lifetime downloads are still running, in line with its category: the median Booking & Events plugin keeps 0.8%, across 944 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Booking & Events plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 38 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

I am a property photographer and I also do floor plans and some video. Tried out the free version which is good but doesn’t allow certain things including accepting card payments. Purchased Business Medium and it adds much more functionality and customization options. The get the best out of it helps to know a bit about HTML and CSS as you need to dig in to the Advanced Mode and configure things “manually” to get it to look and work just right. My knowledge of HTML and CSS is quite basic and I struggled a but but the support is unbelievably good and fast. They helped me configure things and provided me with some code to copy and paste. I still had to figure some of it out on my own but the help form support is top notch and they respond quickly. I tried out some other booking forms but I settled on this one as it has extensive options and flexibility and a good back end where it is easy to keep track on bookings, availability, etc. Would highly recommend this plugin – at least try the free version to start with as that will help you make up your mind if it is right for you.

I recently took on the challenge of developing my own website for my vacation rental. A key feature of the website was the booking calendar for my customers. After reviewing various plugins and weighing the pros and cons of each, I decided that WP Booking Calendar would be the best choice. Since I had never worked with a booking calendar before, I was entering uncharted territory. WP Booking Calendar offers extensive documentation and videos on configuring the calendar, but there were specific nuances related to my business that I struggled to navigate. At times, I felt lost regarding how to implement my desired modifications. I reached out to WP Booking Calendar Support multiple times, and they provided prompt guidance on making the necessary changes, including assistance with my shortcodes. Thank you, WP Booking Calendar Support! You helped me get my website up and running promptly.
