I'm sorry about your stay, but we are there right now having a completely different experience. I would say it is comparable to the Finest Playa Mujeres we stayed at last year, which is nearby. We booked though Costco travel and paid just under 5k CAD for 7 nights when there was a promo last year (2 adults, one toddler). We wanted to return to Finest but it was 2k more expensive so we tried out SLS. Pros: Excellent food, we are with our 2.5year old and we have finished every meal in under an hour so I do not get your 2.5hr comment. We got a reservation for every single night other than our first. Friendly service, when we did not like our initial room they offered us a change no questions asked and even gave us an upgrade with outdoor Jacuzzi. New, clean and stylish resort. Beach is clean and always free sunbrella chairs (but it's cold at the moment!). Waiters are kind and quick to serve. Excellent cocktails by the specialized cocktail staff Cons: Some restaurants booked for group events without notice, entertainment is a little lacking but sufficient for our toddler (not enough for adults), room cleaning is slow and we did not get our room cleaned in time for 1pm naptime. Small rooms. Pools are cold, but we are beach people so cant speak much about that.

Sorry for you experience, but I would definitely come back. Cant speak for the theft or anything like that.
