Hi azsleepless,
You're probably wise to avoid the Hyatt Grand Bed which is not much different from a "normal" Sealy Posturepedic. In most cases ... hotel bed purchases are disappointing and like all major brands they contain a lot of polyfoam which is subject to early softening and breakdown. There really isn't much value there. If you did want to replicate your experience at the hotel ... at least for a little while ... then you would also need to buy the
whole ensemble here
(or at least the topper or feather bed depending on which one you slept on and probably the triple sheets which will also contribute to the feel of the bed). This would add even more layers that were subject to softening and early breakdown. there ae also a lot of unhappy people who have bought this mattress and complain that it feels nothing like what they remember.
Without the specs (and they don't reveal them ... not even the coil count) it's not possible to approximate the mattress and because it also contains a completely different material ... it would be difficult even with the specs because latex and lower density polyfoam have a completely different feel and performance characteristics. In essence though it would be a pillowtop with a soft topper over firm innersprings (likely the DSx) and that's about as close as you could come. Quite frankly you could do better "replicating" the mattress just by lying on some of the Sealys in the store and adding a topper or a featherbed and even though this would also be poor value ... it would be better than the Hyatt.
What I would suggest though ... rather than trying to replicate a "feel" from memory ... is to start from the beginning and test for the pressure relief, alignment, and overall feel that you need and prefer. While your own testing is the best reference point ... with your lower weight you may well prefer a top layer on the softer end of the "normal" 19 - 24 ILD. With side sleeping a 3" layer would also be the thickness of the comfort layer I would test first. A thinner comfort layer of 2" may also work but you may need a slightly softer support core to make up for the lack of thickness. While it likely won't be necessary with latex ... you could add a topper as well if you find you want to fine tune the mattress feel (there are many possibilities here). I would also try a latex core which will feel different from an innerspring to see which you prefer.
With latex ... at least you can have confidence that a mattress that meets your needs and preferences will stay that way for a very long time.
You also are fortunate because there is some very good value available locally in Phoenix.
