*Pre-trip planning with dedicated concierge CMs
*Lounge for concierge guests only that offers continental breakfast in the morning, light snacks during the day, hot and cold appetizers and wine and beer in the evening, desserts and cordials (Kahlua, Bailey's Irish Cream, etc) later in the evening. Some lounges are open all day and night and this allows you to grab a can of soda or some juice at any time; some of the lounges are only open during the appointed serving times.
*Robes for use during your trip
*Dedicated On-site CMs who will assist you with ADRs, show tickets, etc.
*Nightly turn-down service (this is available upon request also to any guest in any of the deluxe resorts, but is automatic when staying concierge).
*In some of the resorts, the rooms in concierge building or floor offer a "better" view or room location (this is not necessarily the case in all deluxe resorts AND often times the "better" view is a higher booking category = $$, but not always; each deluxe resort's concierge rooms are located differently within that resort).
*Access to the concierge lounge from the moment you arrive even if your room isn't ready yet, to the moment you leave on your last day, up until midnight of that night.
That's all I can think of for now...
If you're considering concierge, which resort? I/We could give more specific info if we knew which resort you'd be staying at.
Edited to add:
If you're staying concierge at the Animal Kingdom Lodge you'd be able to book the Safari Sunrise excursion; if you're staying concierge at ANY resort you'd be able to book the Wildlife Discovery excursion.
