We are planning a WDW (& Universal) trip for mid-May. We have good friends in Orlando who would love for us to stay with them, but our DD also wants the experience of staying in one of the Disney properties. We arrived at a compromise by staying 2 nights with our friends and 3 nights at a resort. However, the logistics are a little daunting. Questions: 1) We won't need transportation from the airport when we arrive, but we do want to utilize it back TO the airport from the resort. Can we do it one way only? 2) On the day of the "switch", we will be driving a rental car to MK, then leaving mid-day to do check-in at the resort. Does the whole family have to check in together, or can one of us take care of it while the rest stays in MK? 3) When we have to return the rental car, then get back to the resort, can we get a taxi to do that? Is there some ID we have to show to get back into the resort? Thank you!
