We had a private event (a wedding related event with 100 people) on the Seaport Elite. Overall, the actual experience was quite good and all our guests had an amazing time. However..., there was a mixed bag with planning and event coordination.
Pros:
The boat itself is very nice. It looks nice, the views of Boston are great, and the food was tasty. There was enough space for casino tables, dance floor, bar, and dining area. The viewing area had heating lamps and was comfortable to stand outside even on an October day. The staff were kind and communicative once on board the ship, and all the guests were taken care of. This made it so the guests and my fiance and I were very satisfied with the event itself. Everyone had a really enjoyable time. Certain people were excellent at communication and checking in with us, I will specifically call out Jonny Beres as a point of contact who was very helpful and easy to communicate with.
Cons:
The communication with the event coordinators/planners from City Experiences were very poor. They were extremely unresponsive and failed to deliver on many items. For example, we hand crafted a specific playlist for the DJ to play but the event coordinator failed to send our playlist to the DJ (so none of our songs were available once on board). They event sent me an email saying they sent it, but once we asked the DJ on board he said he never received it. The event coordinator changed the table arrangements, removing a table without communicating this properly. We had printed table cards and assigned seats that had to go unused and we only found out 15 minutes before everyone boarded the boat. We were also never told about having a gift table or card box, something that was an option but we had no idea about. Because of this, we actually ended up not receiving gifts and cards from our guests which are now lost forever (including some other items that were brought on board). The company claims they were all given to guests prior to leaving the boat, but I have contacted our guests and no one has them. Additionally, we were promised a bridal suite, but it was not communicated that the bridal suite had to be setup so we did not even really get to enter it or use it any point.
All of these miscommunications and misplanned items left a bitter ending to an actual great night. We were able to overcome this and still have a great party. I would just choose this venue with caution or be prepared to handle more details yourself
