So sorry that you've had this bad experience. Hate to say it but this does not sound like a reaction to ant bites at all but rather to bed bugs. Suspect that the unpleasant ant invasion was just coincidental. Ant bites hurt and you're not likely to get bitten by ants that come into a home, least of all at night while you sleep. OTOH, it's not unusual for people to have an allergic reaction, itching, significant hives, and/or infected spots from bed bug bites. Having more bites on your limbs (or face) than on your trunk is classic with bed bugs. Sorry.
Remember: Bed bugs are not about cleanliness; they're pests that hitchhike into a space and reproduce there. Dear lady, if it were me, I'd immediately get ALL luggage out onto the balcony and all dry clothing into clothes dryers to kill any hitchhikers that you may have brought with you to the new condo. Damp or wet clothes need a longer time in the dryer. Examine your empty luggage and other belongings thoroughly. Then check the bedding of your new bed. If in doubt, also ask the resort for a complete change of linens (used sheets & towels) and explain that you've just found out you were recently in a room that may have had bugs and you're unnerved, wanting to make sure nothing is in your new room. It's a nightmare but far easier to address this soon after recognition and BEFORE you risk returning home with a hitchhiking bed bug. Again, bed bugs have nothing to do with cleanliness.
What was the resort front desk or manager's reaction when you told them you had bug bites and insects in the room? They're your first and most important contact. The exchange or rental service (such as II, RCI, Hotel.com, Priceline, ThirdHome, etc.) is the next best contact, if you don't get a satisfactory response, especially while you are still there.
