In Heidelberg the parade will be on Tuesday. If you want to be there , have fun. If you want to do anything else, be prepared that the downtown area will be extremely crowded, the stores will be closed and the buses and streetcar won't run to schedule.There will be music and dancing in all the pubs along the main street.
If you want to avoid this, you can either hide in your room or run away until Wednesday. Then life gets back to normal.

Thank you very much for your attention. I'm lucky then that I will join the Carnevals.There is an old saying in Turkey '' A blind prays God for one eye and God gave the blind two'' . :))) Thank you again. I checked all your advices and all of them very helpful for me. Thanks a lot.
