Ask a friend who recently applied for an Austrian visa to help me solve the hotel.

Please ask any friend who has recently applied for an Austrian visa to help answer the question of the hotel reservation confirmation letter and prepare to travel to Germany, Italy and Austria in the summer vacation. This is my first application for a Schengen visa. Which of the three countries is easier to apply for a visa? My real main tourist country is Austria, but I saw on the Internet that the requirements for signing the Olympic Games are very strict, and I have to ask the hotel for a confirmation letter of payment reservation. I'm actually going to make a general trip from Munich-Florence-Salzburg-Vienna, and then find four hotels where I can cancel my reservation, and then cancel it after I get a visa. Because I'm going to drive around Italy with my friends in Austria, the trip will be very casual, and I'll stay at her home in Vienna. If you have to issue a paid hotel reservation letter, it will be very troublesome. Please give some advice to friends who have been to the Olympic Games recently! Thank you very much
