Greetings. I had the same concern when I traveled to Alicante, and I completely understand wanting to avoid hidden costs or blocked deposits. After searching for a while, I found an option that worked perfectly for me. You can rent a car in Alicante without deposit, and the final price already includes insurance, protection, and taxes. What I liked most was that there were no surprises at pickup – the price I saw online was exactly what I paid. They also have offices not only in Alicante but in Torrevieja, Benidorm, Calpe, and Denia, which makes it really convenient. It gave me peace of mind during the whole trip.
