I think that's a great decision. Getting the Deluxe may take too much time away from the parks for eating. So this time go enjoy your meals and the parks. Then you can decide if you want to explore restaurants and cuisine for the next trip.
Though you didn't ask I'll still share some or our meal experiences with you:
Boma - We had dinner there after leaving the Animal Kingdom. It is a very quick bus ride to the Animal Kingdom Lodge and since the park closes around 5pm on most days you have to go somewhere so it was a convenient dinner plan; no issues with wanting to stay in the park and having to leave just to eat. We had our ressie for 6pm, we actually left the park after 5pm (Nemo ran past 5pm) and weren't rushed or stressed to make the meal. They also serve breakfast, so you could choose Boma for breakfast before entering the park too.
Chef Mickey's - We had a late breakfast there. We'd had a really long park day and night the day before so it as nice to sleep in a bit. The meal was really good and the characters were awesome. Though I hope to get to Crystal Palace on our next trip for the food, Pooh and friends don't excite me like Mickey, Minnie, Goofy, Pluto and Donald who were at Chef Mickey's.
Narcoossee's This would be a really nice adult meal and comfy for the picky eater as well. The food, service and atmosphere are just amazing. Keep in mind it cost 2TS credits. We had booked an extra meal so we paid cash ($6) for our 5yo to eat. He only wanted pasta and a drink, it was better to save that TS credit for the buffets we booked.
Coral Reef Not a character meal, but the underwater setting and full wall aquarium are really cool. This is definitely a place that kids and adults can enjoy. We had lunch there and left nothing on our plated!
Again you didn't ask, but if you were considering any of those places that information helps!
