For anyone who stresses about lines at islands of adventure I can do them on the busiest day in under 4 hours. This is what you do get there like 30 minutes early and as the park gets crowded. Marvel island is the most crowded so be careful. Run to spiderman first because it usually has the longest lines and get a fast pass for hulk. Go all the way to dueling dragons and do both fire and ice. Right now it should only be like 10. Since people wait to after lunch to get wait hit all three big water rides as they will not even have 10 minute waits this early in the morning (River, adventure, dudley do right and popeye). AFter these rides it should be like 11:30. Take a 30 minute lunch break as you need to rest and refuel. Then use your hulk fast pass and wait about 30 minutes for Dr. Doom and now its 1230. This leaves you 30 minutes to check out the cool stuff at seuss landing no decent rides for adults but cool stuff. The most important thing to not do at islands of adventure is to do the three big marvel rides first because you will travel with everyone else and have long waits. Hope this helped
