This looks right to me. Nice work finishing up the feature!

@randomsync You'll also need to manually remove check_in_experience_travel_claim_redis_client_refactor from dev, staging, sandbox and prod. See step 3 here: https://depo-platform-documentation.scrollhelp.site/developer-docs/feature-toggles-guide#Featuretogglesguide-Removingold/unusedfeaturetoggles

Please @ me if you or someone on your team doesn't have access to argo in an environment and I can do it for you :)
