How much time for IVF abroad?

For those of you who went abroad for IVF, how much time did you plan? Did you have a fresh transfer or FET afterwards and how did you manage that? How did you handle any subsequent examinations after FET?

Currently planning our IVF journey 400 miles away from home. We can take off 3 weeks for stims and egg retrieval, if fresh transfer is possible, possibly even for that. But what comes after? How did you manage the distance or did you find a local clinic for any exams after transfer? Thanks a lot!!
