The “women” didn’t have time Wednesday afternoon before the start of the Passover Sabbath to purchase the things they needed for the body. So Luke 23:56 likely occurred the day after Passover, Friday, then they rested after dusk which began the regular Sabbath.
This shows another huge hole in the two sabbath theory. If indeed there were two sabbaths that week, the women could have went to the grave on friday and prepared the body then. they certainly would not have waited until sunday morning when there would have been a stink to the body, since that was the 5th day since he died under your theory.
The tomb was sealed and guarded. Even if they had went on Friday, they would not have been permitted to enter - indeed it would have taken some time to remove such a seal as described.
