Do they still sell the button for $1? I have bought the button. But it seems like so many places now ask to keep your change that it does get a bit annoying (not just at WDW). I don't mind donating to the causes that are important to me, but no matter how much I appreciate the cause I cannot support every organization. Personally, when I am on vacation I don't really want to be bothered with solicitations for donations. I understand and value animal & wildlife organizations (thats why we belong to the st.louis zoo) I guess for some guests this will be a bonus incentive for going with the meal plan ;
I can also see some guests who are not all that familiar with WDW being put off, like others have posted, a bit of a nerve to ask for a donation after you've just laid out a tidy sum to bring the family to the theme park.
BUT many people must be giving or they wouldn't keep doing it.
