If hotels put Full-mattress plastic covers on their mattress’,

would that prevent bed bugs?

Your local health department would have more information than the WDW resort board will likely have. This fascinating topic is as hard to get rid of as those little critters!

no. Here's a quote from wikipedia (I know it's not the most reliable source, but I've read these same info elsewhere.)

Bedbugs travel easily and quickly along pipes and boards, and their bodies are very flat, which allows them to hide in tiny crevices. In the daytime, they tend to stay out of the light, preferring to remain hidden in such places as mattress seams, mattress interiors, bed frames, nearby furniture, carpeting, baseboards, inner walls, tiny wood holes, or bedroom clutter. Bedbugs can be found on their own, but more often congregate in groups. Bedbugs are capable of travelling as far as 100 feet to feed, but usually remain close to the host in bedrooms or on sofas where people may sleep.

And GO BIG RED, fellow Nebraskan

It's not the mattress itself that attracts the bedbugs, it's the juicy human in the bed. They'll stay out of sight until feeding time, and as you can see in the quote above, they don't necessarily even hide in the mattress & bedding.

but if you wrapped yourself in plastic, it would keep them off of you
