we did a split trip 2 weeks ago, 5 days Universal, 7 WDW. We are a family of 4, DH can eat a LOT, DS/15 is a hot dog/chicken finger guy, DD/20 is a grazer( smaller stuff throughout the day) and I am your typical 3 meals a day. We brought food for the room for breakfast ( tho I did not eat in the morning 4 days as doing FJ and I get motion sickness) we were on site and had a cooler for milk. the places we ate at Citywalk were:
Nascar $68 ( forgot to use our
AAA there

)
Margharitaville $79 used AAA
Ice cream $18 USED AAA
In parks we brought grapes from room/groceries, goldfish, some poptarts, whatever we had from the room that we felt like carrying) and we got cups of ice EVERYWHERE! My kids love slurpees so we dropped a small fortune on those ( and they are NOT included in AAA)
Only TS we ate at was:
Bula Bar and Grill at Royal Pacific $42 ( does not take AAA)
Mythos $52 ( drank water, but all 4 had huge entrees)( also, not doggie bag/boxes here, so do not order more than you think you can eat)
the rest of the time we did counter service, can't remember each place, but basically the pizza/burger /hot dog route, did get chinese at one place, but would notrecommend it...spent under 65 a day for 4 people.
At WDW we spent more, I noticed right away that we were spending say, 35 for each counter service vs 30 at Universal. We followed the same cups of ice plan, brought some snacks in...actually we found ourselves spending a LOT of time getting ice cups, lol...and those slurpees!
TS we ate in WDW were the Fountain in the Dolphin ( 20% AAA disocunt) ate there 3 x's, no bill over $30
1900 Park Fare..LOVED this, total was $125 incl tip
the rest was counter service...and we stayed under $80 a day...but we did hit the mainstreet bakery for dinner one night ( best random dinner choice ever, lol)
Sunshine seasons at Epcot, was more expensive than I remembered.
Overall, we found WDW to be higher for similar food..by say 10%. With the heat, we were eating at all weird times, getting full from ice and slurpees...but did not buy a lot of pop..I had juice in recloseable bottles that we woud pour just enough for flavor into the ice cups...was a good refresher. It averaged 98-99 ( heat index much higher) when we were there and no rain, so it was hot and that affected out eating. I had alloted $100 a day( including groceries we purchased on arrival) so was happy we stayed in that budget. Meal Deal woudl have been a waste for us for sure. One place we did not eat at was Dagwoods, which we should have as we should have gone a non-fried route one day and there sandwiches looked really good.
