We are at that point in our life, almost all of our travel spend is going to Disney right now...
If the multipliers are "okay" (as in better than what they have right now), I would likely switch as I know we could use the points easily to defray travel expenses...
Would be interesting if they did something like:
$300 Annual Fee
$20/month Disney Bundle Credit
3% back at Disney
3% on Gas & Groceries
1.5% back on all other purchases
