Uml analysis class diagram - associations

[FR33M4N]

**I have attached the UML Analysis class diagram** - Probably a lot of this wrong with it.

This is for a walk-in booking system not an online reservation system.

Normal Booking scenario:

User/Member gives information to receptionist. Users can book up to a month in-advance.

Receptionist searches user/member info. Receptionist must be logged in to search user/member or make a booking.

if details are found the booking continues as normal, if not user details are added to the users file.

Booking time/date/type is then checked for availability. If available then a booking is made.

Extra:

There are two types of staff account 'normal-user' (Receptionist) and 'admin' (Manager).

Manager can reset staff account passwords and create new staff accounts.

Manager can edit session details on the timetable (time, date, type) etc.


Question:

Are my associations/generalisations correct thus far? Would I need to create another class for the swimming pool timetable.
