We had an ARD for around 8:00. It wasn't that busy then, but it did get busy by the time we left. If you're in doubt about how busy it might be, make an ARD while you're there.
We went to Boatrights on 3/6 around 10:00am on a same morning adr, and it was about 15 minute wait for us. But walkups were being told it was about a 75 minute wait. It was rather busy there, and the breakfast wasn't even as good as everyone says. For me, not again...but that's just my opinion.
Just got back 02/21 to 03/08 and had breakfast at Boatwrights nearly every day between 10:45 and 11:30 am. We never waited more than 5 minutes. Parks early entry then nice breakfast.
Boatrights makes a great breakfast. Make ADR on your room phone, but even if you don't we've never had more than a 1/2hr wait. And this is even after 9:00am!
If your worried, make your ADR on the phone in your room and you should have no issues!
I suppose timing means a lot--but when we eat there it's around 9:00AM and sometimes we walk right in and other times a 5-10 minute wait. But a general answer to your question is yes-it is busy.
Our waits have always been minimal, but we also visit at a slow time of the year. If you are worried about a wait, please make an ADR. Stress shouldn't be a part of the Disney package. Enjoy!
I've only eaten breakfast there once, and it was early, around 7:30 I think, so the place was empty. And even 90 minutes later when our group filtered out it was still empty.
Of course, this was during MouseFest, so it was a pretty empty time of year anyway.
They were very busy at different times. I made ADR's for 9 when we had days we weren't going to the parks so we never had to wait. An ADR is the way to go even if by chance it turns out to not be busy. I highly recommend the stuffed french toast and the sweet potato pancakes. My dd loved their strawberries and cream too.
