Hello and welcome to planDisney, Erica!
Good job checking the tip board. I believe it is an excellent way to get an idea of the “climate” for your favorite attractions before your arrival.
If I had to guess, I would assume that the attractions you have mentioned are some of the most popular (must-do) attractions that can become unavailable when it comes to
Lightning Lane purchases (depending on the day you visit). If it helps, guests can make their Lightning Lane purchases the morning of their visits starting at 7:00 AM. For example, I have been able to secure the Lightning Lane option for
Guardians of the Galaxy: Cosmic Rewind two times so far, but do not forget it is a part of the virtual queue. Also, the standby line for many attractions is still an option.
Please return should you have additional questions; we are here to help if you need us.
Have a magical day!
Raquel
