That's really not practical since this is just a seasonal problem. Disney isn't going to spend millions building and operating additional restaurants simply to alleviate over-crowding which occurs for a few hours per day on the busiest park days of the year.
I am curious about your objections, though. How is being personally escorted to a vacant table any more taxing than hobbling around the restaurant in search of an empty table (or more likely, waiting to pounce after someone vacates a table?)
Obviously you have not tried to travel with pain. This is the second time I will travel to a Disney park following surgery (surgeries following an accident in June of 2008). For me to stand is painful - and I have little chance of even walking from the lobby to the room without a rest. Yes, the surgery was not convenient and yes, we have had our reservations for 10 months and yes, an ECV is the solution.
Now, take a minute and imagine standing around while my DH is in line getting food. Have you noticed, those lines move slowly and it will be a great deal of standing - FOR NO REASON - for me.
Personally, to make me stand while I could be seated and comfortable is a GREAT DEAL different than just entering the restaurant and limping to the table to wait. You try it.
Every single Disney vacation involves standing in lines, be it attraction lines or restaurant lines. As a father to two small children, I really don't see how this is any different than standing in line for Test Track, Peter Pan or Haunted Mansion. I've seen more incidents over the years from a single parent who tries to balance too many items on a tray than I have from small children colliding with other diners.
My comment is - if there is a problem with no place to sit - perhaps Disney should employ those Pixies of years past to find a solution.
There is limited optional seating around the park. Most of the big seating areas are connected to restaurants. Perhaps they could create small, shaded areas with tables and chairs for those of us who need to take a break during the day.
With as much as
Disney vacations cost, make sure you get your pound of flesh before you leave. Bonus points for making the Cast Member--who is simply performing his/her assigned duties--openly cry during the altercation.
