Hello. Yes, that is correct. It depends on the location, but generally, if you leave your luggage at that time, it will usually arrive the day after the next day, even in major cities.

Yeah from what I’ve been reading you have to be ok without that bag for 2 days. Just pack concisely and use a bag that is easy for you to carry or pull. Army roll your clothes so you can fit it all in one bag so you can keep all of your stuff handy. Unless you are going for two weeks or more and you have another bag to use for the first few days.
