I stopped at White House Landing last year, only because I was low on food after losing more than a day detouring around un-fordable streams. If I had to do it again, I would not stop there.
My biggest problem was that the owners were extremely unfriendly. The woman was okay, but the man was clearly upset to have to deal with thru-hikers. I think he may have been nicer if I had spent the night there, but I just went over for lunch and resupply. I guess I didn't know that this was really more of a hostel than a restaurant/resupply point.
The burger itself was huge, and well worth more than the $5 they charged. The boat ride over was free, although you may get scowled at and sworn at by the owner. They have a limited amount of resupply food - candy bars, ramen, etc. It is all pretty expensive. They charged me $2/min to use their cell phone, and mistakenly told me that there is no phone at Abol Bridge (there is!).
Also, although the guidebook didn't mention it, their boat service is only for a few hours of the day. It's something like 11:00am - 2:00, and 5:00-7:00 (although I don't know the exact times).
Personally, I wouldn't go back unless I absolutely had to. I don't know if the owners were just having a bad day, or if they are always that surly to their customers. There is excellent camping all around that area (especially on Nahmakanta Lake nearby). I would camp nearby instead.
But that's just my opinion.
