You tell a group that anything is fine, then discover the chosen plan involves something you strongly dislike. Changing it now affects bookings or other people's expectations.
State the preference that matters while plans are being discussed. Distinguish it from a requirement. You might prefer a quiet venue while needing step-free access; those details should not be treated as equally optional.
Offer useful flexibility
Say where you can adapt and suggest an option that answers the main concern. Avoid making everyone infer your preference from reluctance after a decision is made.
If you do not yet know what matters, ask for the details before agreeing. Once the plan is chosen, raise a new issue promptly if it genuinely changes your ability to participate. People can accommodate information more easily when they have it early. A clear preference does not guarantee the group will choose your first option, but it makes the planning conversation more accurate and reduces agreement based on a statement you did not really mean.
