Need specific booking/reservation plugin. Any ideas?

Hi all,

I spent quite while searching for a booking/reservation plugin that fits the requirements below and kind find one. I would not mind to pay money for the plugin. ANY help is greatly appreciated.

– The whole process needs to be within one form.
– Customers need to be able to select between two different course types.
– Customers need to be able to select the amount of people attending, final price needs to change accordingly.
– Customers need to be able to asked to opt-in for the newsletter.
– Customers need to be able to pay via PayPal (either deposit or full price)

Until here Gravity Forms would do the trick, but now the last and most tricky requirement:

– Customers need to be able to select a date for the course and the admin needs to be able to block certain dates, so customers are not able to book those. Already booked dates need to be blocked as well.

Again, a big thank you already. I hope someone knows a proper solution.

regards,

Jan
