In the spirit of Baldurs gate, unlimited rests are fine BUT!!! :
I wish there were at least <CONSEQUENCES> to long rests for SPECIFIC AREAS in the game. Like...Baldur's gate (not mirror like! just in the same concept.)
Some kind of interesting encounter, the flow of TIME (day to night/ night to day...), some drastic STORY or DIALOGUE IMPACT due to resting so much. Getting ROBBED maybe. Some areas completely LOCKED to unlimited rests. etc...someone else can get way more creative ideas.
Firstly
You have the OPTION to turn on/off unlimited rests, health regain after combat, field of view in the dark, food spoil etc..when you start the game with these special difficulties <heroic paths> options. These are AMAZING for immersion purposes, ease of use and difficulty.
Secondly
The game checks to make sure it's okay to camp in that location at that time and will give you the option to access your Stash or go directly into rest.[2] Generally the party may only camp in unpopulated wilderness locations. While resting in the wilderness the party is safe from the surroundings, since there are no random encounters[1], but creatures may re-spawn in certain areas if you do so, however, this won't always be the case.[3]
+1 to all of it.
