Has anyone ever had the option to pay to upgrade at check in (at any of the properties - SR, S, or D). I used to be Marriott plat and am now just a gold, and we would regularly get upgrades to one of the suites at SR or a room w/balcony at S&D. We will be traveling with our 3 year old who is a prompt 7pm sleeper, and it would be nice to have the balcony to sit on when she goes down. We are definitely willing to pay and it seems all of these rooms are available for our dates in mid-May right now (we are planning on using a cert to book a basic room on points). Thanks for any insight/experience!
