I definitely don't want this situation to cause anyone to NOT have a good time.
However, I feel like we're nearing an accord...so I'm going to try...
Chris, as for your worries about spending the entire day at Disney and then back to the house for the party, thereby rendering yourself exhausted, you can have my bed Thursday night for a full nights sleep, and depending on how late we/you stay up Friday night/Saturday morning, you can have either my bed or Jose's bed and then sleep in as late as you want on Saturday (considering in this scenario, we wouldn't have plans until Sat evening).
As for your worries about missing some of the party because of staying til close at Disney on Friday, the party won't start until you guys get back. Sure, there will be people there and food and drinks being eaten, but obviously, the party won't go into full swing until you guys get there (in costume). We'll schedule the party to start at 9, so if you guys stay until park close, get back here and get into costume, it should only be 11ish. Also...it might not be preferable, but shaving prior to heading out to Disney will cut some of your down time.
As far as not being a fan of going to concerts...here's the deal. Even if those of you who aren't fans of going to concerts in the first place, hopefully you'll be able to meet the boys in SoulSwitch the night before, and see they're a bunch of really awesome people, which might make you WANT to see them, especially on such a grand scale opening for two national acts. Your support of SoulSwitch is also support of Jose and myself. On the other hand, Guavaween is also a giant Halloween party, so you could get a second night out of your costume, or even wear another! Worse case scenario, if you absolutely refuse to go to the concert, we will check in to the hotel prior, and you can chill there for the night, BUT, that would be super lame for all involved, because everyone wants everyone involved in everything. I wouldn't have any fun knowing that you're at the hotel by yourself on Halloween night.
Obviously, there are still kinks that need to be worked out, but whatever needs to be done to make everyone comfortable with this situation, I'll do it.
Oh yes...as for a car being available, this can also work if we do Disney on Saturday as well as Guavaween, albeit would be much more difficult to find eachother.
