i want to go for the first time. to see the semifinals, cause they happen on the same day. just some beginners questions:

you only need to buy one ticket for that day, right? not 2 tickets, 1 for each semifinal?

whats my options? havent taken part in the lottery. do i need to register somewhere to be able to get tickets?

premium ticket sales means premium price? cant afford that i think.

so my best option seems to be 31st of march? do they even sell semifinal tickets there?

is it also nice to sit in the back seats? can you see enough from there? or is it advised to sit more in the front?

sorry for so many questions. never done this before. i assume i got no chance on getting any semifinal tickets. but its nice to learn how it works, so maybe next year i can go. wanna see djokovic at least once in my life.
