don't think i would go back.. huge sargassum seaweed problem they only mentioned a day or 2 before we arrived made the beach totally unusable. we had the lux 1 bedroom suite which wasn't bad but had bug issues with the bed on our last night and had to demand a new room for the night which they accommodated. food wasn't bad but one night one of the restaurants was closed with no notice because they changed the work schedule and some of the workers had gone home and they couldn't contact them to come back (according to the concierge) but it was pretty dead while we were there so it could have just been a cost savings measure.
Sushi was horrible as if it was made by someone who never had seen real sushi before, but the more local type items were quite good. the fine dining restaurant was a bit underwhelming. the sommelier there introduced himself as "robert mondavi" which i thought was pretty funny, i almost told him my name was Dominic Perignon but i don't think my wife would have found that funny...
The golf course looked well maintained but we didn't golf while we were there. outside eden roc there wasn't much going on in the cap cana community, the marina was totally dead except for a couple small shops. The zipline at the nature park was pretty fun.
from what i read now, the seaweed thing is pretty common so to me it just wouldn't be worth the risk which other options out there. they seem to down play it a lot, every day it was hopefully tomorrow we can open the beach when in retrospect there was absolutely no way that was going to happen and i'm sure they knew that.
