You can't spoil a vacation buy not having all the trappings. It's how you recharge by not having all that stuff to deal with.
We never did really get into the deal of full hook ups, we stay in places that don't have all the amenities. Much of the time we are in places that don't even have water and toilets. It is harder to get to some of our favorites now that we tow the 30' Brick.
We have hung on to the idea of making do with what you have and making it last. As Ryan says, LEDs and 2-6Vs can keep you powered for the better part of a week. Doing dishes in a dish pan and using the grey water to flush the toilet makes the water last a lot longer.
There are tons of ideas on how to make do with less and you owe it to yourself to see as much of this world as you can.
By the way we are fully qualified to be seniors, but that don't mean we got to grow up, uh old.
