I'm really confused by this. I am at WDW right now celebrating my grandma's 90th birthday. She is in a wheelchair. There are 8 of us in our party. We have not gotten on anything faster. At JC the cast member offered us a
DAS (I guess that's what it was-she offered us a return time) but we actually had FP so we were able to go right in. We went in the wheelchair entrance of iasw but there were other wheelchairs, too, so we had to wait. The safari at AK is always a much longer wait at the wheelchair entrance. The show seating has not been good in the wheelchair areas. Spaceship Earth usually requires a longer wait. Almost every single ride requires us to go through the regular line, so I do not understand this OP at all.
And the buses are no fun to get on with a wheelchair. I know this can be contentious here, but having to wait for a bus with room for a wheelchair and then hoping that the driver will even see that we have a wheelchair is nerve wracking. We had a terribly rude driver at AK who acted really put out by us. Plus my grandma is embarrassed to use a wheelchair (she doesn't in her daily life not at WDW-just a walker or cane) so she hates being loaded on the bus with everyone watching. Then when we get to our destination, we have to wait for everyone else to get off before we can get the wheelchair unstrapped and then get off ourselves.
So, if you are fortunate enough to be at WDW and no one in your party needs mobility assistance, please have a little sympathy for those of us who are just trying to have a good time together as a family. Trust me, it's a lot harder getting through WDW with a wheelchair. It's a lot easier to travel without a wheelchair, but I wouldn't trade this time with my grandma for anything.
