How much would Las Vegas activities cost?

I'm planning on staying 2 nights. I'm into activities like riding roller coasters, going to the aquarium, going to the top of one of the towers and see the city, riding the monorail, and stuff like that. I’d do activities during the day and night for about 20 hours total (about 6 hours per night and 4 hours per day). I’m not going to Hoover Dam or anything, just on the Las Vegas Strip. I'm not going to see any shows or anything like that. Don't worry about the whole vacation price or hotel or food or anything, just activities. So I want to know the activity price only for that. Don’t tell me the price of each activity, just tell me about how much 20 hours of that stuff would cost total. If you want me to add more details let me know then I’ll post them then you can answer the question. Thnx
