It’s looks just like the picture above. It is in the festival in the Rose Garden at 5pm and the reception is in the same area in the Rose Pavilion right after. Please don’t confuse the Rose Garden with the English Rose Garden. They are 2 different things. A helpful reference is It’s located directly behind the chapel with the high steeple points.
It’s going to be a big weekend so cell service will be tricky, and/or lagging, and/or not available due to so many people at the festival. So take pics of your tickets so not to need cell service to pull them up to enter
YES! There are places to stay that even have a shuttle to/from the festival just in case. You can always bring a tent and camp out as well or sleep in your car at the campgrounds.
