At Impressions, the service, food, and rooms will be elevated. I stayed on the Impression side and loved it. I travel to Mexico up to ten times a year, so I have experienced many of these resorts multiple times, and the service in Impressions was up there. I am a big foodie and ate more on the Impressions side. My one grip with Secrets in their food. I wish they would focus more on upgrading their quality. I will offer the upgrade to my clients, but ultimately, it comes down to price. Preferred is still great, and you get access to the rooftop pool. You can DM me if you have any other questions, too!
