Appointments+ and marketpress/ multiple slots for providers without dummies and different hours


I purchased the appointments+ plugin, but have a few things that I really need and was wondering of adding marketpress could solve them.

I read on another thread that adding marketpress will give me the ability for multiple slots for a provider. Will it also give me the ability to have different hours for a worker for part of the year?

Bookings go out as far as 2 years, and my client has different hours for summer than the rest of the year.
