while (Parking != 'Y' && Parking != 'y' && Parking != 'N' && Parking != 'n')
Since user has to input when it's not one of the 4 characters.

I cannot seem to get my loops to work correctly
How do you know? Your code doesn’t compiles :-)

Anyway, the most of your loops are correct, only the first one is wrong:
while (roomType >= 1 || roomType <= 3);
It needs to loop as long as the user inserts wrong answers, not correct ones.

You missed a lot of semicolons - just read compiler warnings / errors: they can put you on the right track.

The biggest problem is you don’t catch the return values from your functions, so they are calculated, but they never get into main().

Other two points I think you should pay more attention to are:
1) don’t let any variable uninitialised (it’s not mandatory, but very helpful);
2) do not declare any variables until you really need it.
