Considering you're paying out of pocket, I'd take the Beaches & Cream ressie. It'll be much cheaper than Homecomin. Plus, if you decide to do Homecomin later in your trip, it should be easier to get an ADR for it than B&C (since B&C is so small, tables fill up fast). However, while I think the desserts are great at B&C, the food was only so-so for me (basic diner food) and I thought Homecomin's food was better, but not to the point it would be worth the price out of pocket.
