We were at TTR 3 times last year (Jan, April and Sept). We have booked again for this April. For lingerie night, there is a casino in Nice Shoes bar for about 90 mins and you have to be dressed in lingerie to get into Nice Shoes. Once that is finished everyone moves into Paty'O bar to party. You don't need to be dressed in theme wear to get into Paty'Os. Have fun and participate if you can, Theme nights are a blast when everyone participates.
