I think you have tweaked your itinerary into perfection (and I'll have to tell Thom that he played a small role in changing it
).
Your ADR's look fantastic! We've eaten at Tusker House twice now and have it enjoyed it both times. And I think you'll really like PrimeTime Cafe!
Don't worry about the interaction -- I think that the servers can read when people truly want to play along!
Anyway . . . have a fantastic time and enjoy this time with your DH!
