Hey there Max,
Welcome to planDisney and thank you for your question! I'm happy to hear that you'll be able to take advantage of the ! My family and I are using the same promotion for our visit this summer.
Like all theme park tickets, these tickets also need to have corresponding theme park reservations set for each day of their use, and you can see the current reservation availability on the
Theme Park Reservation Availability page. If you click the "Kids' Summer Ticket Offer" button, it will show you days that have available park reservations for this special offer ticket.
As you mentioned, it does look like there are no reservations available from June 1-4 for the Kids' Summer Ticket Offer. These are unfortunately subject to availability and reservations can get booked up, as we see on these dates. In my experience, I have not seen booked up dates become available again, but I would recommend
reaching out to a Cast Member at the Tickets line to discuss what your options might be - including if you're considering upgrading your ticket to a standard ticket. They will be able to see the full details of your situation and offer some suggestions.
During your visit, make sure to check out
Bluey's Best Day Ever! at Fantasyland Theatre followed by some Bluey-inspired bites at
Troubadour Tavern. I've heard great things about this show, and it'll be a must-do for families with young kiddos.
Thanks again for your question, Max! I hope you have a wonderful time on your upcoming visit to the Happiest Place on Earth.
Have a Magical Day,
Greg
