Anyways back to the point of the post, we now like Dallas a lot more because we found the companion bathrooms located by every restrooms we saw. Mik particularly liked that they were large including having space to roll his wheelchair up next to the toilet to transfer over.
There was also a ledge to put backpacks and such down without actually putting them on the ground.
The auto flushing annoyed him as usual, but he did like the sink being a sensor to turn on. However, the sink still did not work all that well for him with the soap being far away and not with a sensor and the faucet being somewhat of a stretch and he has reasonably long arms. Overall, though, that is minor when all that really matters is not having to decide what restroom to go into because your only companion is not the same gender as you.
