Relax you are going on vacation and will have many more. You can expect many "Welcome Home" over the coming years. Start looking at your points usage over the next 3 years at least, maybe get a spreadsheet together to lay out your points planning/usage.
Your vacation style will change over the next few years as your kids get more involved with school activities, as you invite family/friends to come along on trips, as you want to go to other places, and you need to prepare for these changes.
