We had an absolutely incredible time in Belize and San Pedro. Barb and Rosa's outstanding communication and support with local connections and tips was just incredible and made our stay so fun and easy.
The Sunset Beach Resort has everything you need! Our unit wasn't fancy but it got the job done. No sargassum while we were there, a nice pool, a beautiful palapa dock with hammocks and we saw sharks and rays in the water almost every night!
Location -- very quiet. A couple of good restaurants and a small corner store with basics are close by but that's it. Feels far from town even though it isn't. It's a drive into town, only 15 minutes but wouldn't recommend walking, it's dusty and/or hot. Most people rent a golf cart, but IMHO a bicycle is equally fine for most trips (even Secret Beach) if you are willing to ride/travel light and don't want to spring for a cart.
Services -- the condos are all privately owned, there is no central check in area, you will contact the staff individually at their direct numbers for everything. There's a swim up bar at the pool but it's BYO and alcohol is fairly expensive on the island. Be flexible and prepared: buy your liquor in the duty free and download all your movies/content in advance. Most places on the island have decent public wifi but don't plan on having your Netflix etc unless you download or pay for cell data. We didn't have any problems on the island itself but the resort wifi IS surfing only, streaming is not possible (which is noted in the description).
Activities -- We visited Lamanai with Searious Adventures, the ATM cave with Tropic Air, and Hol Chan/Shark Ray Alley, all absolute musts! Mixed reviews from locals on Secret Beach but we went for it, we had a blast and highly recommend it. We thought the road was not nearly as bad as some made it sound, took us ~45 mins from town and you can stop at Croc's, Paco's, Marbucks and the Truck Stop along the way.
Spots -- so many options!! Crocs and Carlo/Ernie's both have NFL Sundays and great food. We also loved the Blue Water Grill, Neri's, Caliente's, and Robin's. Drinks at Iguana Juan's were the best we found, really a step above with great service and recommendations. Some decent supermarkets, you don't need to go without anything but I couldn't find a USB wall charge block for the life of me, could be just me.
Four instead of five stars because we had some minor issues at the resort that we chose not to complain about, feedback sent privately. Having Barb and Rosa's help to plan really made everything worth it. There's so much to do and see in Belize that we needed more than 6 days! We will definitely be back. Thanks again Barb and Rosa!!
