[Golf] How much do apartment community golf practice facilities cost?

Our apartment community golf practice facility uses QED equipment.
1 lesson bay / 6 practice bays : All QED
1 month (55 mins x 15 sessions) : 70,000 KRW (charged via maintenance fees)
If you purchase a single session: 7,000 KRW per 55-minute session
I currently pay 70,000 KRW and practice 15 times a month.
I do feel like 15 sessions might be a bit much. Although, I personally tend to go all 15 times.
I think it would be good if they offered 10 sessions for 50,000 KRW.
Anyway, how much do you pay per month for your apartment community golf practice facilities?
