I'll chime in on a few questions:
For my mini-IVF, I have been told two separate things about a 3-day wait between retrieval and transfer. 1) That they transfer on Day 3 (let's say retrieval is Mon, then transfer would be Thur); or 2) That you wait 3 days between the procedures. I'm waiting for clarification. Am waiting for clarification!
Co.oper nurses will tell you 2 days of bedrest, travel on the 3rd. This is contrary to the scientific evidence, which has found NO differences in preg. rates related to bedrest/no bedrest. Lots of the leading clinics say it doesn't matter. I plan to fly home the day after transfer!
There is a cluster of hotels about 1 mile from the clinic, which you can bid for on Priceline. If you type in Marlton, the actual name of the area is Mt. Laurel (Cherry Hill area). There is a great Whole Foods grocery/deli right between the clinic and hotel area.
