Booked Desire Pearl in October our first ever, panicking now

Right so we have booked Desire Pearl in October our first ever lifestyle resort week and I am sitting at the kitchen table at half eleven on a Tuesday night in Stoneybatter making lists and getting nothing done. Tea gone cold beside me. The dog wants out. I am freaking out. Here is the situation. Four years in the lifestyle in Dublin, small circle, comfortable. Booked the week because herself has been wanting to try a resort for ages and our anniversary is in October and the flights from Dublin to Cancun came up good in January when we booked. Eight months ago felt aspirational. Three months out feels real and I have a list of forty things I do not know. The questions I cannot find good answers to. Clothing for the resort, what actually do people wear at dinner, casual? black tie nights? what is the deal with topless bottomless on the beach in practice not in theory. Tipping, how much for what, single dollar bills how many to bring. Public versus private play and how it actually flows, I have read the website I want lived experience. Drinks all inclusive how do people not destroy themselves, freisin we are not big drinkers but a week is long. Dietary, herself is celiac for real not trendy, how is the food situation. Couples to meet beforehand, is there a group for our week or do we just turn up. The first night, when do you actually start, dinner one and dive in or is night two more typical. Comfort levels for first timers, do people there clock you as new and what does that mean. And the bigger thing nobody talks about. We have a circle here at home. Going to a resort feels like opening a different door, not bad but different. Some couples we know have gone and come back and never quite went to the regular events again. Some came back fine. What is the post resort comedown if there is one. My uncle visited last weekend and asked about our holiday and we said Mexico beach holiday which he believed, but the lying is going to layer. Going to bed now. Will read replies tomorrow at work between calls. Brand new to this format of holiday entirely, herself is calmer than me but she is asleep with the dog. Thanks in advance to anyone who actually writes something useful.
