I don't know, we always had seasonal membership and parking. You should call ABG directly.

Two hours should be allotted once you are inside. Also add time for sitting in the traffic jam outside of ABG on Piedmont (it's BAD).

March and April

Yes

I think it's a fine time to visit, but weather patterns change from year to year a little bit. I took a look through my photos for the last 3 Marches. I have a striking photo from March 21, 2019 taken in the garden at an evening event. I know it was a little chilly but there are women in dresses. There are literally hundreds of tulips in the area I photographed, near the blue glass Chihuly fountain. There are also hundreds of white daffodils in that photo, as well as blooming fruit trees (plum??). In March 2018 I was in Austria, so I can't comment. In March 2017 I have photos from the garden and on street on March 5, 2017 of tulips. And lots and lots of orchid pictures from the Fuqua Orchid Conservatory for 2017. Orchid Daze is in February and I think runs into March??? Worth taking a look at their website for the dates as they pull out all the stops.

January is excellent, just dress warm and take a raincoat with a hood and umbrella in case in rain. Remember what do you do when it rains? Wear a raincoat.

Just went a couple of weeks ago and your phone is enough. They will scan the bar codes from your phone

Hadn't seen it at night but I'm sure it's wonderful either way.
