I don't think this is a good way to think it. If black hole is big enough, there is nothing strange happening in the event horizon, no significant length contraction, nothing.
Some "infinities" of singularity are at the center sure, but all the maximal Relativistic effects are at the EH surface. It's even proven that the entropy (informational content roughly) is equal to the EH area divided by the number of planc-length square areas, as the amount of quantum arrangements of information that are allowed "inside". That is a HUGE hint everything's remaining on the surface.
For example, when you see a clock fall into a BH you see it stop ticking at the EH, not at the center. It's a common misconception that everything about them is at the center, but everything interesting is at the surface.
I think you misunderstand what Holographic principle says.
Even if all information is encoded in two-dimensional surface that forms the Bekenstein bound, that does not mean that anything changes when you cross the area. It only means that radiation which black holes emit can't emit information of the matter it has absorbed.
If Event Horizons can come in any number of dimensions (with the conventional things we call Black Holes having 2D of space-like degrees of freedom on the EH) that leads to the obvious conjecture that our 3D universe might itself be a 'manifold' (projection) from a higher dimensional 4D space (i.e. we live on a 3D EH). That 4D space might even itself be a projection from a 5D one, and so on. This is extremely similar to Holographic Principle, but very definitely a more generalized theory.
