I've tries Skedda. Now using Zapla.
Zapla is the simplest system for our purposes so far.
But neither are perfect.
Ultimately will probably develop a system for our private member network. My goal is a single sign on solution - i.e. once a member logs in they can book a room and it is automatically billed to their account and shows up in their account transactions. With Skedda they were sent out of the site where they had to login. With Zapla they stay on the site, but have to reenter their email and credit card info.
So I did a work around with Zapla where they merely enter their name, an email comes to me to approve the booking and I manually complete the transaction in stripe.
