We too are WDW vets and will be heading to DLR for our second trip in June and I have to say that I agree with what lalasmama said. What I found out while planning our first trip is that planning for a DLR trip is so much different then planning a trip to WDW. Where everything is 180 days out or so to plan your meals and such, it is more like 60 days is the start of when you can really start planning your trip for DLR (i.e. make dining reservations, the park hours are up, you will have a better idea about any closures/refurbs that are scheduled). The only thing we have set in stone so far is our resort reservations (we are staying at VGC and since we are DVC members we booked our room right at the 7 month mark because it is really hard to get into there if we waited), we do have a tentative plan placed but of course once our date rolls around to where we can start making dining reservations and park hours are posted, I know some things will change.
As for Soarin and Grizzly Run, I am crossing my fingers that they both will be opened by the time we arrive in early June. Just like everyone else, we are already dealing with the closures of the DL Train and everything around Rivers of America that I really hope these other 2 attractions won't be closed too.
