We are staying at WDW but would like to take one day and go to Island of Adv. We can go on Wednesday or Thursday before Presidents Weekend. Are main goal is to see HP, of course. Which day is better to visit? Do you think there will be large crowds? What type of wait times should we expect if we get there for opening. This is our first visit = any tips? I know we shouldn't bring bags but what do you do with your cameras? Thanks
