I am a complete newbie to climbing but when I saw basecamp's friendly logo and clever punny sayings on the outside I decided to give it a shot. I bought the two week package with my friend. The beginner class was about 2 hours long where the first 1.5 hours was spent on knot tying. The next visit after the class you can get your top rope belaying certification.
The package is best enjoyed with a partner so you can belay on all the walls. I really enjoyed rock climbing over the two weeks and I think I will continue.
Pros
Downtown location
Friendly staff
They change the walls pretty frequently
Cons
I have to agree with another reviewer that the beginner side seems unnecessarily crowded when compared with the "expert" side which is really hard and significantly less used. The busiest times are right around dinner.
I wish the staff would wear nametags so I could remember them better. They're great people and always willing to help. The instructors are great too.
