Wow - Marcie! What a magnificient place. Your enthusiasm comes through - AGAIN!.
Photo tip for flash - if you are taking a photo through glass or a mirror, use your hand to block the direct flash into the glass. It will diffuse it so you don't get the flash effect on the glass/window/mirror. Don't cover it but put your hand a few inches, flat out, in front of only the flash part. Really good if on a bus tour and shooting through a window.
