Was Jesus crucified at a bus station?

I have 13 days left in my trip to change my mind, but I won't: the Garden Tomb is my favorite place in Israel. When you walk into the garden through the gate on the stone pathway, you're surrounded by flowers and shaded by rubber trees and palm trees. Our tour guide led us over to a platform at the edge of the garden, next to a small cliff.

"We do not know for sure that this is the place of Jesus' crucifiction and tomb," he said. "Millions of people think so, and there is compelling evidence that suggests that it is. But first I will tell you what we know for sure: Jesus Christ died, he was burried, and in three days he rose as our Savior and Lord. That's what we're sure of, and the rest is useful speculation."

Here is the Biblical criteria for the location of the cross and tomb:

Jesus was crufied outside of the city at a place called Calvary (Gargatha), which means simply "The Skull." He was burried at a nearby garden, which was owned by a rich man. The tomb was sealed by a stone, which we know from archeological evidence was an unusual type of tomb.

Here is how The Garden Tomb fulfills that criteria:

It is located outside of the city. The little "cliff" has indents that make it look like a skull (you can still see the two eyes, but the mouth is now covered. Nothing else tells us that it was known as The Skull, but it is an intriguing observation). The garden is adjacent to the skull-like cliff, and was owned by a rich person. (They know this because of the water system and wine press that they excavated.) And finally, archeologists know that the tomb is at least 2,000 years old, and though it is missing the stone that sealed it, it has grooves which would have acted as a track for a rolling stone.
Even though this can't be counted as evidence, I definitely felt a certain power and presence in the garden, unlike anything that I've felt at the other holy sites.

So what's up with the bus station? As it turns out, the image that we have of three crosses on a hill is entirely unlikely. Everything that historians know about Roman crucifictions suggests that Jesus would have carried a cross, but would have been nailed to a tree near the street, at eye level. The Romans did this to make a point to the passerbys, who could look directly at the person suffering. (The point being, Don't mess with the Romans.) If so, and if this was the location of Jesus' death (on the street level of The Skull), then Jesus died at what is now a bus station.
"This isn't a holy site," our tour guide said. "It's a bus station. We don't have much information about the place of Jesus' death and resurrection... it's as if the disciples weren't very occupied with the geography of it all. Any why would they have been? They had their Jesus back. This is, at the very least, a useful image of Jesus' death and resurrection. The important thing is that we serve a living Savior. Even if this isn't the right empty tomb, the right one is also empty."
