Leveling up fast to level 100?

Question

I need to train my Umbreon, Espeon, Jolteon, and my Vaporeon up to level 100 for the Eevee friendly coming up this week. Even though all Pokémon will be lowered to level 30, I still want to level them up to level 100. I've battled the Elite Four with them once already and they only went up a few levels. Is there a faster way to level my Pokémon up in a matter of days without cheating?

*Ok, here goes...

• Train a Pokemon received in a Trade. The first obvious choice is training a traded Pokemon. Pokemon received from a trade with a different Trainer ID will receive more experience points than Pokemon you catch in your own game.
• Increase your Pokemon's affection in Pokemon-Amie. Another way to get extra experience points from any Pokemon in your game is to increase the Pokemon's affection in Pokemon-Amie. Play games with it, pet it, and feed it until the hearts are filled up. You can check a Pokemon's Pokemon-Amie stats when you try to switch to another Pokemon at the Pokemon-Amie menu.
• Give your Pokemon the Lucky Egg. The Lucky Egg is a held item that will increase the experience points given to the Pokemon at the end of battle. This item can be found in the Coumarine City Hotel.
• Use the Exp. Point Power. If you use this O-Power, Pokemon will obtain even more experience points after battles, but only for three minutes after using the O-Power. This O-Power can be obtained in the Anistar City Pokemon Center.

Use these techniques to gain more experience than usual. Your nextstep is to find some high level battles around Kalos.

• The first option is the Battle Chateau. Battle a number of trainers each day to increase rank and find tougher trainers. You may even run into some Gym Leaders after becoming Marquis(male) or Machioness(female) rank.
• The second option is Restaurant Le Wow in Lumiose City. This restaurant cannot be entered until you become the Pokemon League Champion. It is recommended that you choose either a Triple Battle or a Rotation Battle. If you choose Double Battle, you'll only fight two Pokemon per trainer instead of 3, and you'll miss out on fighting Pokemon like a lvl 63 Audino, which gives a huge chunk of EXP points.
• The third option is to challenge the Pokemon League again and again.
  'If you don't want to go through scrolling down the completion credits and you're leveling up a Pokemon to a level around 40 or lower, train in the victory road cave next to the league. You might even run into a shiny!'

Certain Pokemon will yield more exp. than average Pokemons, such as Luvdisc near Cyllage city (for lower lvls) and Basculin, in the pond in Laverre city (for intermediate lvls).

One more easy way to level stuff up:

Put one or two Pokes in the daycare, go to Centrico Plaza in Lumiose City, stick a coin or something in the Circle Pad so that your dude keeps riding in a circle, and leave it overnight.  Your Poke(s) will be at least lv. 70 in the morning!
