Tables in Wonderland

Yes because it saves money on beverages and appetizers plus it automatically adds the gratuity. I love the TiW card

How many people will be with you? I would say yes probably. Will you have drinks with your meal? You will 20% off of them too. Do you get a discount on the Tables In Wonderland card?
Oops, just saw a family of four. I would still say yes. Our dinner at Jiko for two is usually close to $200.

I am not really sure. We got ours in MK where you can make dining reservations.
They will also warn you not to lose the card because there is a $50 charge to issue another one so keep it in a safe place.

Just googled it and it looks like you can only buy them in the parks, DTD at guest relations or through the mail.

Yes, because it is valid at so many more CS and TS places, that you will use it often. I love mine but I did not renew ours because our next trip is DL and it is not recognized there. I will wait till we go to WDW again.

Also, I just noticed two of your choices are not listed as taking it. I do not see Yak & Yetti. And the Gospel Brunch does not take it on Sundays. You may need to do some math to see if it will save you anything according to Allears.net.

I was just looking at the list also. I don't see T-Rex, unless I missed it.

Technically speaking, the break even amount to spend for TIW:

$375 if the TiW was purchased at the passholder price of $75.
$500 if the TiW was purchased at the FL Resident/DVC Member price of $100

The 18% gratuity is calculated pre-discount, sales tax is calculated after discount. Because the tax is calculated on the discounted price, the break even amount is actually lower:

If you pay $100 for TIW, due to the tax savings, the break even is actually $467.50, not $500.
If you pay $75 for TIW, due to tax savings, the break even becomes $350.63, not $375

We always buy TIW, as it is good for 13 months, and we use it for 2-3 trips. No problem getting to the break even amount for us(especially if we have a bottle of wine with dinner a few times). I usually tip 20% anyways, so the discount covers the tip every meal.

Same here Skunk. Just usually a few martini's instead, but I've been known get a nice Port after dinner now and then!
