sol.pelicanos.ocas@melia.com email them and ask.

I had a single room there about 4 years ago and ended up in the ocas, didn't seem to matter though they're well linked. I requested a low floor and got a ground floor room and as a result, didn't get much of a 'balcony' just a view of a wall

since I was there, the place had a bit of a refurb so my reply is probably of no use to you, but what I can say is that I stop in single rooms regularly and the ones at the Sol pel/ocas where better than the others I've stopped in, well designed and more spacy than most.

have a good time and please post a review, I'm hoping to go sometime and may well stop there again.
