Quoted from someoneelse:1) Complete FOTR MB (All eight members+Gandalf Balrog Strike),
achieve Super Jackpots for an Elf Gift at minimum
2) Complete TTT MB (Survive the Assault to the end, new level every 5
jackpots achieved), achieve Super Jackpots for an Elf Gift at minimum
3) Complete ROTK MB (All Seven Levels), achieve Super Jackpots for an
Elf Gift at minimum
4) Play all 6 Rings Modes (Completion not required)
5) Play There and Back Again (Completion not required)
6) Collect all six Elf Gifts
7) Destroy the Ring (2X Required, or ONCE if you are SUPER SUPER HOT!)
Valinor starts automatically the moment you have destroyed the ring AFTER having achieved goals 1-6 above.
Basically you should play through all the modes before starting the last of the three main multiballs. If you by mistake start all three multiballs without having played all the modes you can back out of "Destroy the Ring" by starting Gollum Multiball (which will change the ring shot from "Destroy the Ring" to "Mode Start" for the time Gollum Multiball is active). This makes sense to go for if you only have one or two modes left to play. If there are to many unplayed modes left it makes more sense to destroy the ring once, finish the modes and play all main mulitballs again.
FYI, there is a "secret" 7th Elf Gift that must be acquired before reaching Valinor.

It lights the "Gift" arrow itself, and it triggers a cool secret mode.
