Infopath 2010 count number of days listed

Question

I have a requirement for a form to be completed by students.

The scenario is:
There are 3 consecutive days each academic year where Students can try various things. These things may be subject specific or not.
The 3 days are Wednesday, Thursday & Friday.
Early on in the academic year the students must choose what they wish to do and they also must have back up options also.

So for each day there must be 3 choices.
Wednesday  (Option1) (Option2) (Option3)
Thursday     (Option1) (Option2) (Option3)
Friday          (Option1) (Option2) (Option3)

Each days options come from a seperate list held in Sharepoint 2010 with an associated number of days for each item.

What I would like to do is for a check on number of days an option is set to run for then disable the control for the following day in that column.

So if the user were to choose the following options:
Wednesday (Camping3days)        (Fishing2day)         (Cooking1day)

Then the following days would look like:
Thursday    (Hidden/Disabled)      (Hidden/Disabled)   (Option3)
Friday        (Hidden/Disabled)       (Option2)               (Option3)

Is this possible by using Rules or will I need to learn how to do some coding?
