Is it possible to simplify the reservation form?

Yes. You can configure the system so that customers do not need to select price options or fields. Additionally, you can display the resource calendar immediately when the widget loads.

Open the resource settings and enable the Skip reservation step checkbox. For this to work correctly, the resource must have only one price option.

As a result, the price option will be selected automatically, and the order cart will be shown to the customer.

To display the resource calendar immediately, open the widget settings, go to the Content panel, and set the View mode to Calendar.
