Belatedly, let me report how this worked out.
Eventually, I received a response from the address posted by Guy from someone named Letiane, quoting rates, but when I tried to make a reservation, I received no further reply. A month later, I got a message from Rick Simpson in Ubatuba saying to e-mail in English Ozir (the address supplied by filip) which I had already tried in google Portugese. So I wrote Ozir again, in English, and it was as if I had been unblocked from a spam filter, as I received a prompt reply from Ozir, and also from Letiane (
[email protected], who is perhaps the hotel manager). The result is I was able to make a reservation for two nights and one and a half days in the reserve with guide, and did not have to prepay anything.
Prices for two were about 300R/night with three meals, and 100R/day/person for all day visit (half that for a half day). The rooms are nice, the pool pleasant for a few hours in the hot part of the day, the restaurant OK and they did a 5:00AM breakfast for us. Not much in the way of birding on the extensive grounds, maybe there'd be some Parrots if some of the trees were fruiting.
As recommended,I asked repeatedly for,a and was promised, a bird guide, but the two guides (no English) we had seemed more like security guards. However, the first day's guide did know a few of the specialty birds (including parrots) by call, so I guess he's the bird guide. The second (half) day, the guide knew nothing, but I didn't initially realize this, and allowed him to direct us on a long useless drive to the northern edge of the park which wasted much of the morning.
Anyway, we had some good birds:
Red-billed Curassow (easy early AM on road but a long drive from hotel)
Maroon-faced Parakeet
Blue-throated Parakeet (just fly-bys)
Tawny-browed Owl (day 1 guide had a stake-out)
Minute Hermit
Rufous-throated Sapphire
Sooretama Slaty-antshrike
Black-headed Berryeater
Red-headed Manakin
Thrush-like Schiffornis
Turquoise (White-bellied form) Tanager
Major dips were White-necked Hawk and Red-browed parrot (heard only).
We did not attempt to access Sooretama.
Anyway, thanks for the tips and pointers.
