Hotel Del Sol An un-guarded, easily-snuck-into hotel pool in the Marina

Need a confidence builder before going after the Fort Knox of hotel pools? HDS has you covered, with a street accessible, unlocked/unguarded, no-lifeguard, no camera'd, seriously-how-are-there-not-more-homeless-dudes-hanging-here sliver of H20; really your only obstacle here is where you enter -- in order to skip the manager's office, make sure to duck under the giant archway as you head south on Webster, which is gross, but legal, as that dude's definitely 18.
