We had a New Year's Eve wedding at the Sheraton and it was amazing! Everything went so smoothly and that was largely due to the amazing staff at the Sheraton. Katryn, the event coordinator, was awesome to work with! Both my husband and I are in the military, so we planned our wedding from out-of-state, and Katryn was so easy to get a hold of by phone or email whenever we had questions. She also was very accommodating to my parents and in-laws and all of their requests and surprises. Our wedding was definitely way less stressful because of her. The hotel staff was so helpful with set-up and clean up. Everything we asked for was immediately provided and they packed up all of our homemade decorations after the wedding so that all we had to do was load them in the car. The food was absolutely delicious! All of our guests raved about it, especially the prime rib that was huge and perfectly cooked. We had a lot of out-of-town guests and the hotel staff was super accommodating to all of them. Cody, the front desk manager, and Steve, the valet, made sure they were all taken care of and felt at home, just to name a few, but the entire staff was awesome! We definitely recommend taking advantage of their beautiful suites if you have lots of friends and family visiting. They’re beautiful and secluded so we felt like we had the whole hotel to ourselves. Lastly, Katie, one of the lobby bartenders, took the time to get to know us and our guests, which added an extra special touch. She knew what we liked and was so friendly whenever we were in the lobby to meet guests. We had a wonderful wedding and we can’t thank the Sheraton enough!

I had high expectations for our wedding venue and I’m happy to say that the Sheraton exceeded my expectations. I worked with Katryn Treamer who was great to work with from the beginning. I had many questions for her and she was always able to answer them quickly. I really liked that the price for the venue included things that were extra at other venues, such as the cake which was amazing from Jacques, chiavari chairs (with many color options), a great room for the bridal party with food and drinks during cocktail hour, and a large 2 bedroom suite with a balcony, kitchen and fireplace comp’d for our wedding night. I was the only wedding that weekend at the hotel and I truly felt like they treated me like a princess on my wedding weekend. I was in full contact with Katryn who was just a joy to be around all weekend, smiling and taking care of anything I needed. From the front desk to the boys working the valet, service was extremely helpful and friendly. As far as the reception itself, I fell in love with the chandeliers in their ballroom. The space is just romantic and beautiful for an indoor wedding and it hit all of my checklist items. Most of our guests were able to stay over and utilize the discounted rates that the hotel offered to guests of our wedding. I had a lot of people come up to me and say that they loved being able to just walk upstairs to their room after the wedding versus worrying about getting a cab or driving home. The hotel is located within walking distance of numerous bars, restaurants, stores, etc. Our guests had a blast enjoying downtown Portsmouth. We ended up having about 175 people at our wedding and had plenty of room on the large dance floor. I did think the cocktail hour was a little bit crowded so I would say that was the only negative thing my husband and I had to say about the whole experience. Overall, we could not have been happier with our experience and venue choice and I would not change a thing if I could do it all over. We a
