I just returned from our wedding trip to the Barcelo and I have one thing to say: YOU HAVE NOTHING TO WORRY ABOUT!!!! I know every bride says it, but regardless I was still freaking out until we got there and met with Grecia, our WC. From that point on I was stress free because I knew she was on it!!! The day was perfect, more beautiful and stress free than I could possibly have imagined!!! In terms of candles etc. I'd suggest buying them there for sure. Even in first class that allowed a lot of extra baggage, we still had to pay $450 in extra baggage fees!!!! There are lots of markets around Playa, there is even a mall in the hotel!! You should be able to find the baskets and stuff you need there.
For the bride who wants votives, I don't know where your reception will be but it if you want it on the beach it is really tough to keep them lit! I ended up just asking Grecia to do her best and never bought any candles. She managed to rustle up a few but honestly everything looked so beautiful that I hardly noticed!! We had the ceremony on Playa Azul and the reception on Palmeras beach. If any of you have any questions, feel free to ask away!!
Here are some pics. I tried picking ones that will show you the most of the set up and location, since I know those are the ones I wanted to see when I was searching!!
