The 30-day period starts from the first day you come to Doorspace.
If you come more than 10 times within those 30 days, you pay a maximum of €100 excluding VAT for that 30-day period. After reaching the cap, you can continue to access Doorspace for the remaining days until the end of that 30-day period without paying extra daily access fees.
If you come 10 days or fewer within 30 days, you only pay for the days you actually used the space.
