Technically, this particular forum is for any Transportation related to Disney Trip Planning. That also includes discussion about Disney locations other than WDW.
Okay, there's no Disney destination in the Dominican Republic. But we try to be friendly here -- although we also try not to sugar-coat reality.
Over on FlyerTalk, the participants tend to be elite frequent fliers who want to maximize their frequent flyer points and first class upgrades. The OP might be eaten alive over there.
Thank-you for your defense of my post and for all of your help.
I truly appreciate it.

I have found a possible alternative to the split flight and hope that it works out.
I had never even given thought to the possibilities you pointed out, and I took your warnings to heart.
Thanks again!!!
