Free way to add simple Availability calendar (dates booked vs available) to website?

Site URL: http://www.spaincountryvilla.com/

Hi, I've had a linked Ical availability calendar on my holiday rental website for years. It has started to go buggy - takes ages to load or fails to load, and I want to replace it with a link to my VRBO Ical calendar.

I know about Lodgify, but I am not looking for any fancy features eg online booking/payments - all I want is to display booked vs available dates across the whole year + following year. I run a tiny business (one property, 12 weeks availability a year), and my business has been devastated by Covid impact, so I really cannot afford to pay for Lodgify.

Squarespace customer care have not replied to my request for help.

Can anyone advise?

Lodgify has some of the best features for holiday rentals on Squarespace websites, but if you want something simple and cost effective, you could use an Events page (adding events for each week that is booked) and then display these bookings to customers using a Calendar Block. It won't link to VRBO but it won't have any running costs either; just the small amount of admin to update it when you receive a booking.
