Spring Vacation, Spring Holiday
You've seen 夏休み and 冬休み. If that isn't enough, you can see that this is a spring rest of some kind. That would be a spring break or spring vacation.
The reading for 春 is the same as the one you learned with the kanji. The 休み part is the same as the vocab word 休み, which hopefully you can read! If you know those readings, you can read this too.
During the spring holiday promotion, admission is only 1,000 yen for students.
Any of these times during spring vacation would work for me.
Are you over your cold yet? It sucks having a cold during spring break, eh? If it’s still bad, don’t stay up late. Get well soon.
