Prepare a summer guest basket with space for personal things
Offer a few visible essentials, then leave clear space for the things a guest brings with them.

Before adding a basket, make room on the dresser or bedside table. A guest needs somewhere for a phone, glasses, a water bottle and the small things that otherwise disappear into a suitcase. An elaborate welcome arrangement can occupy exactly that space. Move your own decorative objects temporarily instead of expecting the visitor to work around them.
A shallow basket containing a couple of clean washcloths and a sealed basic soap is often enough. Keep it easy to move, and place it where the guest can see it without searching through drawers. If the basket is small, leave the surrounding surface open rather than trying to fit personal belongings inside with the supplies.
Ask about needs without guessing
Fragrance, skincare and hair products are personal. A collection of scented miniatures may look generous but be unusable for someone with sensitivities or different preferences. Ask whether there is anything specific they would like you to have available, and make it easy for them to decline. Do not decant unfamiliar products into unlabeled decorative bottles.
For warm weather, a working fan, accessible drinking water and a place to hang a damp towel may matter more than themed gifts. Explain how to use the room's fan or air conditioning if the controls are not obvious. Make sure cords do not cross the route to the bed or bathroom.
Put information where it helps
A short card with the Wi-Fi details, bathroom location or where extra towels are kept can prevent repeated questions. Include only information relevant to the stay, and avoid displaying passwords permanently if the room is used for other purposes. A clear spoken welcome may be enough for a frequent visitor.
Check the lighting from the bed. Someone arriving late should be able to reach a lamp without climbing over a bag. Clear a section of closet rail or provide a stable place for an open suitcase if the room allows it. These small spaces are often more useful than adding another item to the basket.
After the visit, wash used linens and check what remains unopened. Replenish only the things that were useful. A guest basket does not need to be a permanent stockpile of travel-size products; it can be assembled from fresh household supplies when a visit is actually planned. That keeps it simple and avoids offering products that have sat forgotten for years.
