Disney 100% allows and even encourages it. However, as a non-DAS user I am a little frustrated with the idea that a DAS user can get on more attractions that I can throughout the day (thus encouraging abuse, making standby lines longer, and reducing LL inventory). In my opinion people waiting for a DAS rides should be allowed to experience any aspect of the park that does not have a line (parades, shops, restaurants, any attraction that has no wait time), otherwise DAS will negativity affect non-DAS users.
