Well, not really. The Hawaii longhouse where the CL is doesn't have balconies on the second floor. However, I think I remember reading that if you book TPV and CL then you definitely get a balcony. It was a page or two back on this thread. You could just book GV, and ask for a balcony but leave the specific longhouse request open. I did that last trip and we had a third floor balcony in Tokelau.
Someone else could answer better than I can on the TPV rooms and if you have a better chance of a balcony there - but I hope I helped at least a little!
This is always my debate at the Poly too... Balcony vs. TPV.
According to Disney (with extra info from tikiman's website), the longhouses with TPVs are:
Aotearoa - balconies on the 3rd floor, patios on the first
Tuvalu - balconies on the 3rd floor, patios on the first
Tahiti - balconies on all 3 floors
Hawaii/CL - balconies on the 3rd floor, patios on the first. Tikiman's site shows that there are TPV rooms on the 2nd floor, so if he's right, then the TPV/CL combo will NOT ensure you a balcony.
I'm not sure in total how many TPV rooms have balconies vs. how many GV rooms have balconies, but it seems to me that there are more GV rooms with balconies...
So I tried counting the TPV rooms on tikiman's site, just out of curiosity...
Aotearoa - 8 (1 patio, 2 no balcony, 5 balcony)
Tuvalu - 22 (4 patio, 7 no balcony, 11 balcony)
Tahiti - 46 (14 patio, 32 balcony)
Hawaii/CL - 35 (7 patio, 11 no balcony, 17 balcony)
So counting only non-CL buildings, you have 76 total TPV rooms, 48 of which have balconies (63%), 19 have patios (25%), and 9 with no balcony (12%). So I guess the odds are pretty good.
I think it would be interesting to do this for the GV category and the LV category as well... I might have to do that sometime. I would be interested to compare the likelihood of a parking lot GV vs. the no balcony TP or LV... Those would be my least desired options I'd want to avoid.
Unfortunately I my debate is harder b/c I need/want connecting rooms AND a balcony. I think my odds for that would go down if I go up to a TPV room....
