Back in March, I posted about a problem with payment for Orangerie tix for a June visit. Over several weeks after that I kept trying but just got errors of all kinds. This month I acquired a second e-mail address, a Gmail acct and was finally able to set up the required Orangerie account. Before I was using a .net address which the website did not like. I was then able to purchase tix with the same Visa card I had used before.
None of this was easy. The website is very glitchy, sometimes the calendar for ticket availability would not come up and various other problems. So I finally got the tickets but it was a frustrating experience. The only advice for others I have is to keep trying and maybe use a different e- mail address if necessary if you have problems with the site.
