I haven't been back to the park yet (reservations coming up soon though!) - but my understanding during the time before the parks were open, when it was just DTD is that security wasn't allowing guest-to-guest pin trading. I'm guessing that since CA/DL is still under enforced social distancing that it would still not be allowed.
While WDW started doing pin boards immediately, I've heard that none are out yet at DL and no CM's are wearing lanyards. (If that has changed though, hope someone posts about it!)
I don't think Westward Ho has reopened yet but heard a rumor it could soon.
Capacity reportedly bumped up from 25% to 35% this week when the OC reached the yellow tier, so expect longer lines and still no FastPass/MaxPass.
Re: AP's - DL has announced that a replacement 'loyalty'/membership program will be coming before the end of the year but no details yet.
When I go in a few weeks, I plan to bring a lanyard with a handful of traders on it just in case the pin boards miraculously return. But based on DL aligning with CA's June 15th dates to loosen restrictions (temperature checks, masks and social distancing are all staying until then), I wouldn't anticipate it would happen before then.
Also - you said you have dining reservations (lucky!), but if you plan to get any quick service, be aware that mobile order time slots can fill up hours in advance and take up to an hour for pick up once you signal you have arrived. So scheduled those accordingly. Also, snack choices are apparently very limited at carts right now.
