Looking for tips and tricks. Adult special needs son will be in manual wheelchair with me pushing. Cannot be left at a table alone while I order/pick up meals. Will have an additional person with us so can have her sit with him while I pick up our meals and then she can get hers once I return. Considering the time for me to get ours, then the time for her to get in line and get hers, chances are we wouldn't actually end up eating together and a lot of extra line time, so that isn't really ideal. I doubt the trays are large enough to hold 3 meals, and I'm certainly not talented enough to balance two trays of food and drinks and successfully return to a table. Thoughts on a better solution?
