2 - Part time/drop in at $25/day. I must know scheduling as far in advance as possible. Spots are NOT guaranteed.
The majority of my clients opt for full time, the few part timers, I consider extra money. Depending on your numbers you're allowed and how flexible you can be with money can play a big part of what you allow. I wish I could do the flat rate with everyone, but in my area, it's pretty low income, so that deters a lot of people. I found by giving them the options, I still usually get what I want because people really like the thought of full time and saving money. The premium of part time can be a bonus though. 
This is how I work... I also limit my PT/Drop-in to a max of 3 days week; I have one FT that pays a premium for 60 hrs weekly (Just upped the hrs this month) - FT is usually no more than 50 hrs and ALL my FT pay monthly. My PT/Drop-in pay weekly unless they are doing the premium hourly thing which is paid in advance the day of care lol
