OK- normally we head right out and do "something"- really ANYTHING! Just something that says 'I'm at WDW!!!!" Mind you- this is since we started staying onsite- back in our offsite days- it was more dull upon arrival...more stalling...more checking on this or that.
So, in 2010- we immediately hopped a boat from WL to MK, in 2011- we didn't even go to our room (which was ready at 7am!)...just went straight to MK for breakfast, in 2012-we started exploring YC and BC and popped into Beaches and Cream for ice cream since we had a late dinner and needed a "healthy" snack. 2013 was the exception as we were horribly delayed due to a car accident. We were supposed to arrive mid afternoon, but didn't make it until nearly 11pm. I pretty much flopped on the bed and then decided to "move in" to our room...something we NEVER do! Let me just say how much I regret not "moving in" on previous trips. Made things sooooo much easier! Although, I don't know if I would have moved in had we arrived on time.
