Really the only things to consider would be: If you are planning to use G+ that day, make sure it's purchased prior to 7AM. Some folks have multi-day tickets and buy it for the entire stay in advance. Others have APs or go a day-at-a-time with G+ and have to purchase it between midnight and 7AM of the day they're using it. As for ILL, having an onsite resort reservation is a huge advantage, allowing you earlier access to ILL than non-resort guests..... Then it's just like the old FP+ system, or ADRs - quick, efficient fingers to get what you want! Good luck.
