We used to plan arround cache density having gone somewhere in the early years where it was 15 miles to the nearest cache.
No such issue now so we go where we want to go and look at the local caches after finding somewhere to camp / stay.
For our next hols we have compiled a separate bookmark list of must do caches based on local recomendations and top rated from GUK.
Caching is much cheaper than doing touristy things and you get to see all the touristy things and some good local stuff as well.
We do use gsak filters quite a lot when we arrive though to remove thetypes we dont enjoy.
