So... don't leave us hanging.
Did you go, where did you go, how did it go?
Tell us all about it.

Thanks for all the comments, everyone! I'll give a quick update of what we did/where we went. To make a long story short, we weren't able to take the airplane for multiple days at a time like we were initially told we could. It was kind of a gray area of "yes you can take it for a week" but we were also told, "no you can't take it for a week" so we just stayed somewhat local. It actually worked out well considering we had a couple of minor maintenance issues that needed to be fixed when we returned home a few days.
We went all over Washington, Oregon, Idaho, and Northern California. We did 60 hours in 7 days, which was quite a bit to be in a 152. I really learned how limiting a 152 is when it comes to distance, alternates, etc. After a few bags, both of us, and fuel, we didn't have many options for airports and of those, we didn't have many plan Bs if something was to go wrong at our planned airport (weather, closure, etc). For instance, we wanted to make it down to Salt Lake City area, but considering there was a small chance of thunderstorms and we really had 0 alternate options due to fuel if a storm was parked over the city, we couldn't make that trip.
Overall, it was a great week considering I got to fly with a friend, teach him instrument, and finish up my time before heading off to the airlines. Someone above asked about the service ceiling in a 152--I think the POH says 14,800. We managed to find some updrafts and rode them up to 13,800 feet at one point--had 1,000 FPM from about 7,500 up to 13,800, and even then we decided to stop climbing.
If I could do it over again I would really want to take a 172, but considering it saved us a few thousand dollars I think it was probably worth the savings. Additionally, we were limited a bit more by the high winds in the area because of the 152. The very last day (less than 5 hours from ATP mins), the winds picked up to about 35 knots. We waited it out for a bit, but that's probably the strongest external pressure I've felt when it comes to flying. The temptation to finish my time was strong. The FBO staff looked at us like we were crazy when the metar was reporting 31 and we walked out the door.
Thanks for all your thoughts! It's a bummer it didn't work out quite as planned, but it was still a blast!
