Pretty bad! You might be able to eat at the Lounge at Cali Grill, but you're likely to be turned away at Le Cellier.
Which would actually be your best option at LeCellier....
I do not make reservations any longer, but I also travel solo.
I do see one problem with your plan, some of the signatures aren't even open until 5 or so.
If you do decide not to do reservations here are my suggestions for good, generally easy to get places
1. Swan/Dolphin restaurants. Easy to get to from both Epcot and Studios. Good food, nice atmosphere etc...
2. MK - Go over to the Wave at the CR
3. Disney Springs. Generally early you can snag a table at any of them, especially with a small group.
4. AK - Head over to the AK hotel. I have had a lot of luck with being at JIKO right at opening
5. Epcot. Lots of times if you go ask around 4 at Rose and Crown they can work a small party in. (Nine Dragons is always an option, but it's also not that great, better than Le Cellier, but then so is my local Longhorn Steakhouse!)
Resorts. Saratoga and OKW in particular have TS restaurants that are generally easy to get into.
