Hi there Martine Elaine,
Welcome to planDisney and thanks so much for your question! It's always great to get to help international Guests like you plan their visit to the Happiest Place on Earth!
Not only can you plan your trip as you described in your question, but I often suggest it! Adding in rest days when you're able is a great way to enjoy some pool time at your resort, go see other local sights, and recuperate from long days in the parks.
The main thing you want to be aware of for your
multi-day tickets is that they need to be completely used within 13 days of first use after which point they will expire. As long as you use them within this window, you are free to add in as many rest days in between as you'd like! There are so many fun things to see and do around Southern California, so this is a great way to approach your holiday.
I also wanted to note that the Disneyland Resort will be in the midst of the
Halloween season when you arrive! That will include fun decor,
characters in their Halloween costumes, and seasonal attraction experiences like
Haunted Mansion Holiday.
Depending on how long you're visiting, there is also a special event called
Oogie Boogie Bash - A Disney Halloween Party, which is a separately ticketed event happening on select dates in Disney California Adventure Park. Keep in mind though that if you're interested in purchasing tickets then you'll want to try to purchase them soon as they usually sell out quickly!
It sounds like you are going to have such a fun trip to the Disneyland Resort. Thank you again for your question, Martine Elaine! Come back and see us here at planDisney if you think of any follow-ups. We'd love to help!
Have a Magical Day,
Greg
