Is it possible you are thinking of the Clarion Inn Lake Buena Vista at 8442 Palm Parkway? I think they changed this property a while ago from a Comfort Inn to a Clarion Inn.
If this is the property you mean, then no, they do not have free breakfast. We often do trips here when we are only staying one night and want a cheap clean place to sleep & shower. Rooms were updated recently. Standard rooms have two double beds, mini fridge, coffee maker and microwave. Pool is basic with a cute splash zone area for the little ones. It's always been clean and staff friendly. Depending on season standard rooms range form $39-$79 a night. I always request a parking lot side room as the others face the 4 and can get a bit loud. I just stayed here last Sat. for $39. Really for the price it's a great place.
It's about a 5 minute drive to Hotel Plaza Blvd and three or four minutes more to DTD.
