Hi Malinda. Your trip to Colorado sounds fantastic! I bet your MIL is smiling along with all of you in spirit.
I've only been to Colorado once - the Ouray and Telluride area. We rode our motorcycle there from Montana before kids. It is so gorgeous there.
I have done P90X as written once and I still do some of the workouts on occasion. It is an excellent program and I saw visible results. I did it after my daughter was born and it got me back into pre-baby shape. Tony is kind of a dork, but I appreciate his sense of humor.
I really like all of the upper body weight days and Ab Ripper X. The leg day is kind of easy for me - I prefer Cathe's leg workouts. The yoga day is good, but very long at 90 minutes. I don't really care for the Kenpo workout - I would sub in another kickbox workout for that day. The Plyometrics workout is ok, but you could easily do Breathless Body, which is more advanced, instead.
Today I did some Cathe Lives - #321 Metabolic Circuit and #339 Shock Body Bootcamp. Cathe is solo in both and they were decent high-intermediate level workouts. I probably won't repeat them much in the future, but I had a good workout day. I was expecting Shock Body Bootcamp to be much harder than it was b/c of the name, LOL.
