The OP is asking for a general ballpark of what a person with a family spent on just excursions on
their Alaskan
Disney cruise. Not for anything specific on particular excursions. No one can chime in on what they spent on their excursions?
For the OP, going on how expensive Alaskan excursions are and that on average, you could do maybe no more than 2 per port, you could possibly average it this way:
3 ports x 2 excursions each = 6 possible excursions
@ an average of $200 (ballpark) pp x family of 4 = $800 per excursion
$800 x 6 = $4800 est. for trip in just excursions
Of course, some excursions are more or less, and children prices will be a bit cheaper than adult prices.
