Mid September and October are OK. By the first week in October it has started cooling a bit and humidity is getting lower. Also at Universal studios they do a Halloween Horror Nights special so lots of people are going there at nights.
The least crowded country, or least densely populated, is Mongolia.
Depending on when you go, it can vary. During the summer, waits can exceed 3 hours for some rides. The least crowded time is usually during October, the average wait then is from no wait to 30 minutes at max.
in summers and on fridays, Tuesday being the least crowded with Saturday following nfriday. park in general through the year is crowded a lot. summer break, December, winter break, spring break, etc. but it is definetley worth the trip
Assuming when you say Disney's Wilderness Campground you're referring to The Campsites at Disney's Fort Wilderness Resort, No they don't rent RVs at least not directly through the resort. They do have dealers outside of Disney that you can rent an RV from & they will deliver it to Fort Wilderness but the the resort itself only provides a place to either park your RV or set up a tent.
Pink's Hotdogs in universal city is never crowded
If this is your Spring Break, it will most likely be VERY crowded. Spring Break is the top travel time to Disney Parks. For the least crowded times, try these dates: January (except New Year's Day) until just prior to Presidents' week in February The week following Labor Day until just prior to Thanksgiving week The week following Thanksgiving until the week prior to Christmas
The least busy times at Disneyland are:The first couple of weeks of DecemberFirst Tuesday of September through mid-November (except the 3-day weekend of Columbus Day, the second Monday of October)First full week of January to President's Day, the 3-day weekend which includes the third Monday of FebruaryTuesday after President's Day to mid March (when spring break starts)Mid April through third week of May
Tuesdays
The middle of the week is the least crowded days. I would suggest going either Tuesday or Wednesday for the shortest lines.
Fall will most likely be the least crowded, and therefore best time to go. Be sure to check for special events, such as a food and wine festival in October, they are fun, but will increase crowds. If something is going on, that will increase your wait times at attractions, but events can also be enjoyable. You will have to way the costs/benefits. Also, check school holidays - when kids are out of school, more people will be at Disney world.
Monday
no.all Disney princesses are at least white or black
