Well I just got back...
Coaster count: (2) Did Manhatten Express at night, and yes... it was rough but I'm glad that I went on it. I also went on Speed...the Ride. That was a fun coaster, very quick and the first coaster that I've been on that goes completely vertical at the end.
I did go to the top of Stratosphere. However, I really thought that the High Roller looked to be very wimpy, and decided not to go on it. The other rides however looked to be way to insane for me to try (yes...wimped out) I really did not feel too crazy about hanging over the edge on either X Scream or Insanity.
Best attraction that I did however had to be Star Trek: The Experience. That was a ton of fun. Nice thing was that it is in The LV Hilton that I was staying at. One big complaint of the hotel... bad internet service. There was no WiFi anywhere in the resort, the connection line that my room HAD was all screwed up, and the ISP service in their business center would not hook up to my Mac. The staff there had no clue other than to say..."Yep, we can't seem to get anyone's Mac to work here..." Otherwise, the trip was pretty fun and I'm looking forward to bring my wife on a future trip (It's been 25 years for her as well!)
