How hard it is to replace a toilet?

Is it easy to replace a toilet?

How does the drain line connect to the bottom of it?

[BrntToast]

the drain line is attached to your floor
between that drain line and the toilet is a thick seal made of wax, when you set the toilet down it compresses and makes a water tight seal

So the toilet is just stuck down to the floor with the wax?
Do I just pry it up off the floor until it breaks the wax seal?

It attached to the floor with two flat carriage bolts, each bolt is located on the side of the bowl under plastic caps. Assuming you have shut the water supply and drained the tank just pry off the caps and unscrew the nuts, the pry and lift the toilet of the floor.

Did not see the caps before. 

Maybe I will try and replace it myself this weekend, thanks.
