Clarification on cost

I sent this email out a few days ago, so here you go:

Hello! I just want to clarify a question on the email we recently sent out ("Please Reply by March 14"). Question 4 reads "We estimate the cost will be about $30 per person. Do you consider this to be a reasonable cost? If not, what do you suggest?"

Many people have asked if this cost is just for dinner and so I want to tell you exactly what the cost includes:
1. Reservation of park facility for the lunchtime gathering.
2. Reservation of facility for the evening gathering.
3. Catered dinner for the evening gathering.
4. Program during the evening gathering.
5. Memorabilia for each alumni.
6. Possibly other related items such as decorations, banner, mailings (though we are emailing as much as possible), etc.

What the cost does not include:
1. The website.
2. Meal for the lunchtime gathering. Each family is responsible for their own grub.
3. Travel.
4. Our time; so we don't have the cost of a professional reunion planner.
5. "Where are they now" booklet, which we will probably make an electronic version.

We will, of course, make the cost as low as possible; but we also want the reunion to be a good, quality experience for everyone who comes.
