There's no need in this sort of app, as you know at compile time what the maximum number of anything your system is required to deal with, so you can always use a lookup table of some sort (even if it has an 'In_Use : Boolean' field/discriminant.

Now that is exactly the domain where I would expect to not see access types, for the reasons you cite (as well as related reasons having to do with predictability and the consequences of errors.)
