Where could I park a car for about 2 days ish, without getting towed, near Universal Studios Orlando?

My friend is coming and we dont want to pay 30 dollars per car at the hotel. We want to park one somewhere and then just carpool to the hotel .. but we dont' want it to get towed... It would be from like noon one day to like 10 pm the next day. Any ideas? For free or cheap.. I know wal mart is 24 hrs but I dont know about towing..
