There's a ton of info on this site, YouTube, etc. I'll give you two areas to think about that might help with your thinking: 1) pure spreadsheet math and 2) emotional preferences for vacation.
1 Spreadsheet math
If you're planning to go to Disney for an extend period of years AND you want to stay in Deluxe accommodations onsite, then DVC likely makes sense. Add to that if you plan to stay in a 1 BR (as you've mentioned) and I'll speculate 2 BR later it should work out on the costs. And it doesn't have to be a DVC or bust for vacation for the next 20+ years. We've rented out our points and used the cash for other non-Disney types of vacations. Another thing to consider, you do not have to own these points for the life of the contract. In many cases most families sell after 12 years or so which is at or just a bit past the cost breakeven point if visiting Disney on an annual basis. A last factor that many have mentioned is that if buying resale, the saving vs direct will greatly improve your breakeven time.
2 Emotional preferences
Spreadsheets aside, my wife and I really enjoy
Disney vacations. We did it while the kids were younger and now that they are in their 20s, we still go. I know once they have their families we'll be doing bigger trips. But until the bigger family situation arrives, her and I have been doing couples trips sans kids! And it's fantastic! We've factored it into our retirement plan thinking of golfing trips to WDW (OKW or SSR), Food and Wine Festival at DCA, Halloween to Christmas decorations cut over Oct / November, etc.
In closing, DVC is not a cheap thing to do but if you're going to spend the money at Disney anyways for deluxe resorts then DVC long term should work out. And if you don't buy into DVC, you'll be just fine. Millions of folks go to Disney all the time without purchasing DVC and have a fantastic time. In this day and age, having the financial ability to go via cash or DVC stays is wonderful.
Good luck...
