day of coordinator

A few weeks ago I mentioned that we had recently signed the contract and paid the deposit for a Day of Coordinator. I am extremely excited to have this checked off the list! I knew from early on that I wanted a coordinator of some kind, but was concerned that one wouldn't fit into the budget or that it would be considered unnecessary. Luckily, both my parents were on board with this idea and the future mister and I met with someone back in June.

After our meeting, we decided to go with their lowest package, which they describe as "for the couple with their event professionals and facilities confirmed, but who require a coordinator to facilitate their rehearsal, pre-ceremony pictures and ceremony." More specifically, this package includes:

planning sessions at 3 months, 1-2 months and 1 week prior to the event
unlimited email and phone conversations the month of the event
personalized, detailed timeline of pre-ceremony and post-ceremony photos
personalized, detailed timeline of ceremony
copies of personalized timelines distributed to all appropriate wedding professionals the day of the event
etiquette advice and guidance
complete wedding rehearsal coordination (1.5 hours)
pre-ceremony and ceremony coordination (4 hours)
emergency coordinator kit available at event

Our coordinator will also be able to handle some set-up as long as it is minor. For anything that is more involved or time consuming, our coordinator suggested we hire a second person at an hourly rate. We can also upgrade to full day-of coordination (to include the reception) at any time. This is where I'm torn and would love some advice. Initially, I was very happy with just rehearsal, pre-ceremony and ceremony coordination in order to save some money. After the post-ceremony photos, I figured that the DJ and catering manager could take things from there. But now I'm thinking that an extra $200 might be worth the peace of mind that comes from having a coordinator there for the entire day, pre-ceremony through reception. Which do you think is more important - saving some money or peace of mind?
