When I look at RCI weeks and narrow the SW FL search to only a 2BR+, with check-in between June 15 - August 19, 2018, I only see one option in Fort Myers Beach: Tropical Sands #0721 and the unit is a 2BR 6/6 with twin beds in the 2nd BR (so you'd need to have 2 on the LR sleeper sofa). Having never been there, I can't comment on the place itself.
Stayed at Tropical sands for a week earlier this year. All units (around 40 in total) are identical. All are 2BR and spacious (about 1300 square feet).
That being said, there is very little about the place that could be accurately described as "updated". New flooring was apparently installed recently --- dark, fake wood vinyl replaced the former carpeting. Other than that unimpressive "update", although the place is clean and reasonably well maintained, it is of early 1980's construction and the tired unit interiors certainly reflect that fact.
We enjoyed our stay and appreciated the unexpectedly ample amount of space. Washer and dryer inside each unit. King size bed and attached master bath. Second bedroom is much smaller, with two twin beds and a second bathroom nearby which, although clean, obviously has not seen
any noteworthy changes since the place was first constructed nearly forty years ago.
As previously noted, there is indeed some walking required to reach the beach. Whether it's a "long" walk is subjective; we certainly didn't think so.
In any case, the small number of people on the beach once we got there made that walk entirely worthwhile for us. YMMV.
P.S. One additional note: I don't know if "exchanges" into TSR identify a specific available unit in advance, but be advised that all units there with either the letter "D" or "K" (1D, 3K, etc.), regardless of which one of the (3) levels the unit is on, are somewhat "tucked behind the wall" of their adjoining building. Sitting in the screened lanai of those "D" and "K" units certainly provides shade and privacy, but the only "view" from those "D" and "K" lanais is primarily one of the nearby adjoining wall. Then again, the only "view" from
any unit on the TSR property is only of the pool area anyhow, since high rise condos across the street completely obscure any view of the Gulf. We liked the place anyhow and we certainly enjoyed our stay. As always, to each their own. YMMV.
