Sounds to me like she had a great time and did very well.

Keep reinforcing the recall although not always with treats, gradually phase them out and use other rewards when she comes back, a big fuss, a game of fetch or just being allowed to go back to running around is a reward in itself.

Keep the best treat (food, toy etc) handy in case of emergency until you are confident you can overcome anything that may distract her and above all, enjoy seeing your dog happy.
