Staying in Disney Resort Hotel

Do I have to stay in Disney world resort all the days for which I want to book FPs 60 days in advance? Say if I plan to visit for 6 days and if I start my visit at a Disneyworld hotel for 4 days and stay in non-disney hotel, can I book for all the 6 days, 60 days in advance?

Only check in day through check out day, unless you are staying at a Good Neighbor hotel with this Disney perk. Then you can book all the days of FPPs.

what happens if I stay in another disney hotel for the remaining 2 days. Can I book starting 60 days prior to checkin in the first hotel?

Yes.

Thank you!
