I’m going there today and was glad to learn about the trolley. Much better than fighting for parking. Can’t wait!
If you’ll be riding the Green line a word of advice. East of Petco Park is the 12th and Imperial station. It’s the first station on the green Line and trains leaving there are far less crowded, you’re guaranteed to get a seat. If you board at Convention Center or Gas Lamp stations you will have a hard time finding a seat. If you’re taking the Blue or Orange Lines use 12th and Imperial station also. Have fun!
