This is your husband you are talking about, right? Does he have a great life insurance policy that names you as beneficiary? Then by all means, let him do it.
Seriously, we've driven that way many, many, many times. The area is VERY congested. Let me put it this way - he'd have to 'drive" along Buena Vista Drive. At one time, when we walked from the Swan to MGM (hollywood Studios), my husband insisted (it's always the husbands, isn't it?) that the path went to the Studios. It doesn't - that's only on the Boardwalk side. So we had to go up and cross over the canal using Buena Vista Drive. I'm a city girl and that had me scared. Needless to say, we don't do that anymore.
Could he do it? Probably. Should he do it? NO.
