our family vacations as kids were always camping, sometimes in remote areas, and we were heavily involved in Boy Scouts and Girl Scouts, hunting etc, and camped frequently, canoe trips, extended camps etc. We always made it to Mass, even though logistics and transportation was more difficult then because my parents made it a priority. the only exception was a canoe trip where we backpacked in and out and were gone for 10 days. our troop asked for and received a formal dispensation from our pastor for that one. When I was a GS leader we routinely took the Catholic girls in the troop, after a campout, to a Sunday evening Mass at the one parish on our side of town that offered it, and parents picked them up there.
If this is a weekend activity, not an extended activity, I find it hard to understand why you would be unable to find a Church for Mass, or to find a Sunday evening Mass someplace when you return. Maybe it just takes a little investigation and a solution that has not occurred to you will present itself. My brothers always go to Mass on their hunting trip when oldest brother is along because he insists. When they are on their own, they make it into town for breakfast but skip church. Hhhmmmm.
my dad always made it a point to search out a church or shrine or basilica of historic or other great interest on our vacations, DH and I did the same, and we have many wonderful memories of these, such as Cross Village in Michigan, Our Lady of the Pines, St. Anne de Beaupre in Canada, Our Lady of the Snows, a lovely old church in St. Ignace (forget the name), a tiny church on the Georgian bay in Canada, most recently the beautiful new OL Queen of the Universe right outside Disney in Orlando,
and some of the cute little mission churches in No Mich, Canada, PA, NY, Wis, etc. some of them in mobile homes or the backs of trucks, sometimes in the park ranger’s office, several times on Indian Reservations or with migrant workers in Spanish.
