To the original question, my husband is an engineer (works in software), and I work in higher ed (staff, not faculty). We live in a relatively low cost of living area where salaries are good because they're competing with the greater DC metro area, which is an ok commute from our home. So, we do pretty well, especially because our income is supplemented by a rental property we bought when first married which is now fully paid off.
We live below our means and invest heavily in our retirement savings. Our kids are in public schools, and though we live in one of our city's more expensive neighborhoods, we paid well below the average home price as we have a 'fixer-upper' that will generate a very nice profit when we sell (husband fixed up our last house and is doing the same to this one). We pay cash for used cars and drive them for years and years. We don't have credit card debt. We don't have a ton of fancy electronics; just a few phones with a great data plan that my employer supplements, a good computer, and two TVs that are over five or six years old. Our kids go through clothes like you wouldn't believe, so I buy on eBay or at thrift stores. My husband and I are fortunate enough to work in casual settings, so we don't need suits/expensive clothes for work. Our furniture is mix of Ikea and thrift store items we've refurbished with a few nice inherited antiques. I am a serious bargain hunter, and shop at Aldi or Shoppers (with a weekly $10 off coupon) to keep food costs low. We also like to raise veggies in a small garden.
Our splurges are shoes and occasional travel. Seriously, good shoes that last for adults, and good shoes for the kids even though they outgrow them fairly quickly. We also travel a lot, mostly to visit family...drive to visit husband's family, fly to visit mine. Most of our other vacations are budget friendly; we go to the beach, camp at state parks, etc. We do, however, take a big family (husband, kids and I) vacation every few years (Prince Edward Island, Maine/Acadia National Park, Paris, etc.). While I don't do those on a shoestring budget, I look for bargains. We rented an apartment in Paris, for example, which was much less expensive than staying in a hotel, gave us much more room, and we saved on food costs as we were able to eat in for many meals (and we had a great time grocery shopping in Paris, so preparing light meals at the apartment was fun and not a chore).
I've done two WDW vacations with kids, and one with my husband (my oldest was a baby then, so he doesn't count that as a trip...his younger brother does lol). I go other years with my siblings, nieces/nephews, and sometimes parents and we'll share rooms. Even though I tend to stay deluxe at WDW, it's with an eye to savings. We go in offseason, take advantage of discounted rooms or pay for DVC points. We will do split stays sometimes. When I share rooms on trips without my kids, it cuts down on overall costs. I'm also very lucky to live in a area where I have access to three airports, so I can almost always find very affordable flights to Orlando; for example, last year, my kids and I flew Southwest to Orlando for around $500 total. When just I am meeting up with my extended family in WDW, I usually have enough credit card points to fly.
So, basically, my husband and I are pretty comfortable. But we are frugal in most areas and shop for bargains, even when staying deluxe at WDW!
. Out of State? We can hit WDW twice per year, eight days per trip
