I think we've basically determined that a cont'l breakfast/brekkie
can vary by property, state, city, country. And that Marriott has conflicting T&Cs on whether ROW (aka, outside US/Canada) is cont'l or full.
It's just me, but I'm really not that fussed about whether we get cont'l or full. Is the latter better? Sure. Will 99% of us starve if we only get cont'l? No.
FWIW & speaking only for myself - I'd rather direct my energies to things like getting all spend at all brands to count (which directly impacts our point balances), than bang on about cont'l vs. full. If we're going to do a concerted complaint/fix this, that would be on the top of my list.
Cheers.
