The way we travel now - kids are 12 and 15 - it's about experiences. So not going somewhere to actually see the place but because going there gives us an experience we would enjoy or are interested in. I do think there's a lot to see in this country v going abroad and I've been around including studying abroad.
It's hard to do things without enough funds however I mean it is what it is. If it were me I would look at a 2 year timeframe and budget and save accordingly to plan those thrips out. Do yes, by all means same money and drive to a couple places but also fly to do stuff you like.
We like rafting. You can find a lot of places drivable to do this but you can go west as well. For Europe it's about getting there. Once you're there they offer easy train travel. It's not like it is here

it's easy and even cheaper to do in Asia. So you mix and match but don't go somewhere because of the hype. I mean I once Paris is great but it's not that big a deal where you must see. It only makes sense if you wanted to see and do something only found in Paris. There's so much nature also to be explored and that's def easy and cost effective.
I also think where we are, going to Canada isn't hard. Also going to S American countries - flights are $$ but once you're there it's not too bad. So that kind of thing - really understand budgeting is for transportation and it's possible in certain countries to not break the bank.
It takes a lot of planning. Good luck!
