The rune way portals are an obvious solution but again, they are something that breaks immersion for me. I'm digressing here but the map is littered with these convenient portals that apparently nobody else has noticed or uses? I would much prefer simple way points at key locations that imply fast travel on foot, rather than magically porting about the realms.
I think this is a problem we might have to live with. While I absolutely support the idea of the scenario of the camp changing locations depending on where we rest, think it's more immersive & etc etc, the camp is also implied to be a fixed place. By that I mean that the it has tents, chests, tables, everything that makes it kinda like a "base" for our group. If the camp scenario changed all the time, implying we're always moving places, it also wouldn't make much sense for us to tell NPCs to meet us at our camp, how could they possibly find it? Carrying around heavy chests and tables wouldn't make much sense either. I don't know. I truly get it, it feels weird to be in the middle of the underdark and rest on the forest, but I guess we might have to brush it off as portals n stuff. Unless Larian comes up with a plausible explanation.
The whole static camp concept is just a bit daft thematically; you've literally just dropped out of the sky, have no idea where you are and realise that you have a limited amount of time to find a solution to the tadpole in your head but somehow we have time to set up a static fixed camp adorned with chests, tables, ornaments etc. that we return to each evening because the game does not allow us to rest at any time apart from night. It's like the Fellowship of the Ring magically returning to Rivendell each night even though they are half way through Moria.
BG2 dealt with this in a much more immersive way, companions were told to wait at a specific location or simply told to return to a specified inn. Seeing as we haven't yet come across an inn this would obviously be impossible to currently implement but I don't see the issue with for example, telling a companion to wait at the druid grove. This won't happen because Larian have obviously decided to have all party interactions/cinematics be instigated at camp.
Talking of BG2 I hope that Larian will introduce Class Strongholds, which were a fun and thematic part of BG2 and hugely added to replayability.
