So we have found a provider of an lft to help us get home. We are on Eurotunnel Saturday morning, leaving 1030 ish getting back 1025 ish gmt.
The gov.uk link says three days before.
We can either get them tomorrow - Wednesday between 0900 and 1100 or Thursday same time. Thursday is safer bet but we need to travel then so it feels like cutting it fine. Wednesday is more comfortable arrangements wise but it is on the cusp of 72h and what is 3 days? We'd, Thurs and Fri?
Advice or thoughts please?
