Actually according to our local ABC weatherman, Garth Kemp, there is still a slight chance of rain on
Tues and Wed. but it looks like the chances are diminishing. Thursday has no chance of rain, high near 66. We may not get it at all in Anaheim (or where I live in Riv. Co)
Don't discount DLR in the rain. The parks won't be too busy and you can still ride many rides. Also the rain keeps the locals away! If it does rain check out the Animation Academy in DCA. It's all indoors and there's plenty to do-do the Animation Studio where you learn to draw a character (you get to keep your drawing) They do a new class every 1/2 hour on the 1/2 hour. The class takes about 20 min. Turtle talk with Crush is in the same building.
If it does rain it doesn't look to be a huge storm. Scattered rain. Which means it will be not raining more than it is raining.
If you don't want to go to DLR in the rain you could go to a movie (at DTD or elsewhere), bowling at Anaheim Garden Walk, check out The Discovery Zone in S.A. (have heard mixed reviews on this), or go to a mall (Main Place is pretty close)
I'm sure others will have more possible ideas. But I say if it's raining, go for it. Bring ponchos and water proof shoes (I wear my
crocs in the rain) and hit more of the indoor attractions.
Have fun!
