Here is what we suggest: once you know your moving date, count backwards on how many weeks you might need to use the totes for packing. Most people tend to need our totes for 1-2 weeks to pack prior to their moving date. Now, count how many weeks after your moving date that you think it will take to unpack. Most people also take 1-2 weeks to unpack. We suggest that you book a Rental now based on what you think will happen, and then you can always add on some extra days if required. We have a ton in stock so all should be fine!
