There is some merit into investing from an "hours of fulfilment resulting from the investment" perspective, but if you overdo things, it may actually spoil most of your vacations. If in every moment, you reflect what you could have done, and calculate the hourly opportunity cost instead of enjoying the moment, any money spent on being right under that clear summer sky with romantically sparkling stars on the French coast will degrade to a spreadsheet exercise.
My recommendation: use such considerations in the planning phase, but not _during_ a vacation or date! "Be here now."
