Admin actually posted a list of things to do. If you do a search you should find it. Have fun! - MrsSchnooks  566.2 #194 8:50PM

There's a whole list of things made by admin. But I do have to say more than one pair of shoes. Or shoes that can withstand the water - MarshaMouse  2834.6 #15 9:25PM

as long as you are prepared for it (mentally and clothing wise) you will have a wonderful time. I highly recommend bringing rain boots or other waterproof shoes as soggy shoes are a terrible thing to be walking around with all day. Just know the rides/activities that won't be available and don't let it ruin your day. Disneyland is fun, not matter what the conditions. - Sarafina  398.5 #335 9:28PM

Waterproof boots and waterproof jackets make a cold rainy day cheery and cozy. - Spoonful_O_Sugar  435.7 #283 9:32PM

Some of our favorite & most memorable days in the parks have been rainy days! Just pack a poncho and a sense of adventure! Most rides will be going rain or shine and the crowds tend to thin when the weather turns wet! If you are looking for some fun options away from the drizzle, take in a show or make reservations at a restaurant you may not otherwise make time for! - cmogo  38.5 #4035 8:47PM

For what it's worth, we survived a major deluge last spring with a 5-year-old thanks to the Animation building. While it poured outside we drew characters at Animation Academy, explored the Sorcerer's Workshop several times and hung out with Crush in Turtle Talk. We all had a blast and never once felt like we were just waiting out the rain! - cmogo  38.5 #4035 9:50PM
