Overview
You can oblige people today if you must -- but do not give them the idea that you are someone who can be taken advantage of! Make sure your opinions are known, even if you just give an FYI to people in power. They need to know where you stand. You can go along with the group plans (and it might be in your best interest to do so right now), but that does not mean that you should keep quiet about how you would do things differently.
