Question about Plitvice Lakes new on line ticket system

Oh, boy. We are traveling through Croatia June 6-10 and made a reservation to stay at Etno Garden near entrance 3. I've asked our host to procure tickets for us, and have had no response, so then I went to their new online system for Plitvice Lakes and put in June 7 at 8am and the only options displaying were tickets for children and students. We have made plans around visiting this park, and am a bit concerned that we will not be able to visit. Anyone have any luck with adult tickets in June? Am I just too late? Thanks for any help you may have.

You used to be able to buy a one day or a two day (48 hour) ticket, now on the on-line buying site it looks like adults can only buy a two day ticket (while children and students can get a one day or two day - does't that seem pretty strange?)

The online system wasn't in place when I visited Plitvice ...but ….

I am seeing the option for adults to purchase both 1 day and 2 day tickets. Is this the site you are using?

I checked various dates (2 days from now and several random dates in June) and was seeing Adult tickets available. What date and time did you check? Perhaps the date and time you have chosen is sold out for adult 1 day tickets?

judykupsky, I put in June 7th at 8am and saw availability (Entrance 1: 120 tickets available; Entrance 2: 140 tickets available) for Adult 1 and 2 day tickets. I tried various things to see why you might be getting a different result. I couldn't see what the problem might be. I wouldn't think it would be related to something like which browser you are using, but you never know. You could try a different one.

One place it says you can now ONLY get in with advance purchased tickets, another place seems to indicate this is just an option.

I found this article:
https://www.croatiaweek.com/new-ticket-entry-system-introduced-at-plitvice-lakes-national-park/

Plitvice National Park has introduced an online e-ticket system.
Tickets can only be purchased in advance, at least 2 days prior to
arrival. Entry tickets will still be able to be purchased at the Park,
but with the risk that they will not be available because the number
of tickets per hour will be limited because of overcrowding, daily
Jutarnji list reports.

The text of that article includes this note:
*Tickets can only be purchased in advance, at least 2 days prior to arrival. *
(implies that the only way to buy tickets is in advance, online, with no option for at-the-park ticket purchases)

However, when I go to the source referenced by that article:
https://www.jutarnji.hr/vijesti/hrvatska/uveli-potpuno-novi-rezim-ako-odlucite-svratiti-do-plitvica-i-pokusate-na-ulazu-kupiti-ulaznicu-mogli-biste-se-neugodno-iznenaditi/8831408/

and translate that to English, I get this slight variant:
"visitors can buy tickets online only in advance, two days before the visit."

This (original article) implies that the only option for buying online tickets is to buy them 2 days in advance; they cannot be purchased 1 day in advance or the same day of the visit. It does not imply that purchasing online is the only way to buy tickets.

So, without having seen what you read, perhaps there is a subtle matter of translation leading to confusion about whether tickets can still be purchased in-person, at the park.

Both the English-translated article and the original article (which I then manually translated by Google Translate) go on to say that tickets can still be purchased at the park, IF they have not already sold out through advance online purchases.
