I just want to add that I am pretty sure that any couple that gets married will prefer having their special and unique photos taken by an enthusiastic wedding-amateur with great overall photographic skills than by a grumpy "pro". If the connection between the photographer and the couple is great, the couple won't have to worry and that will show in the photos.
Also the photographers favorite shot is not always the same as the couples favorite. They might even like the photo, where a special moment for them is caught on camera, that you would have thrown away because it was blurry for example.

Denise I hope you get well soon!

Oh and if you have gels for your flashes. They might get in handy when the difference between the red-room and your flash light is too great.
Your bonus with the red-room is that you won't have to worry about red-eyes. It will probably will look better in the picture anyways
