Hello Linda! Thanks so much for stopping by planDisney with your question. I'm happy to hear that you looking to rebook a trip that didn't work out.
Currently,
Disneyland Resort tickets are able to be purchased 120 days in advance. This would be the reason you had trouble booking late June tickets, as it's a bit too far out. The good news is that you will be able to book those tickets in about two weeks.
When you book you can choose One Park Per Day or Park Hopper tickets. You'll also have the option to add a parking pass if you will be driving and parking at Disneyland Resort and
Disney Genie+ to your tickets. I've used Disney Genie+ the last two times in the parks and it has really helped us save time and ride so many attractions. I definitely recommend it if you are only visiting a day or two, so you can really maximize your time.
I see you mentioned VIP in your question. If you previously were booked for a
VIP Tour, they are available for booking by calling (714) 300-7710. This is an amazing experience that really gives you a customized experience in the parks. I did a VIP Tour a few years ago and I loved getting to get priority access to many attractions and hearing so many fun facts and stories about Disneyland Resort.
Linda, I hope this information helps prepare you to book your tickets for your summer trip to The Happiest Place on Earth. If you have any other questions as you plan don't hesitate to reach back out to us!
