We stayed in Venus at Catcha for our 20th anniversary a couple years ago. We fell asleep on the very private balcony, just gazing out at the moon and stars and enjoying each others company (and the rum cream). It was an incredible experience. I hope to do it again for my 25th anniversary in a couple more years. I don't think you can do a walkup there, because they book up pretty fast, and I don't know what your budget is, but it was well worth the extra expense to me and I'll do it again for a future celebration.
