That map doesn't seem so bad to me as long as the players have at least one Druid/Ranger/Cleric to revive people that get knocked unconscious
I imagine the flow will look something like pic related; the players will probably skip the bears (unless someone has Speak with Animals or something, or they stomp the first encounter so you decide to make the bears immediately hostile). So you'll have 3 back-to-back encounters. Probably rough but totally doable, especially if they get at least a short rest afterward.
(I haven't run the module so take my thoughts with a grain of salt)
