Hi Diane
I'm sure you will enjoy your visit, and I would like to add that it is definitely worth viewing the films of the original registers etc. Several times now, I have been delighted to find entries which are missing from the internet-based listings. But beware, it is extremely tiring reading the microfiche in the original handwriting, and very time-consuming finding the exact entries you need. I would recommend spending the mornings in the museum, and afternoons visiting villages/graveyards etc. to give your eyesight a rest. Look away from the screen frequently, and also take a decent magnifying glass.
Have a great holiday, and best of luck with your research!
Susan
