Not that you asked, but for me, it would depend on what time you arrive that first day and what you plan to do the next day. For us, we arrive around noon; have lunch at the resort; do some unpacking and settling in; and then we head to Epcot for a few hours -- arriving there around 4:00. We have our FP's scheduled for 4-5:00; 5-6:00, & 6-7:00 (or somewhere around there). We have a CS dinner there as well. We usually try to get back to the resort by 9:00 and get in a quick swim before getting to bed by 10:30. Then we hit the ground running with a rope drop the next morning. I'm a *huge* fan of having a ticket for arrival day and just making a casual visit to a park for a few hours. It's really handy to visit a park that has FP tiers as you can knock out a Tier 1 ride that day.
That being said, if we were arriving late and wouldn't be able to get to a park until late evening *and* had plans for a rope drop/long day the following day, I'd probably just head to Disney Springs for dinner or just hang out at the resort that night. If we were sleeping in a little the next morning or just had a short day planned I'd be heading to MK that arrival night to enjoy the evening EMH. I'm a big fan of those as well...especially when they go until 2:00 a.m.
