When I made my ressies at the Dolphin, I had the choice of a porta crib or a "regular" one. We chose the regular which is smaller than our crib at home, but definitely better than the portacrib. It came with a sheet and crib blanket. Ours was plenty deep enough. It had been moved to the lowest setting.
I don't know if you will have room for both a swing and exersaucer in a standard room when you already have a crib in there. If you need the swing to get the baby to sleep, I would try to rent one of the new portable swings that doesn't take up much room. Instead of the exersaucer, we just had a bunch of toys that attached to the stroller and would put the baby in there in our room. That also helped with feeding solids, if you're going to be at that point.
