Plan A: keep the day small

Start later, make a food plan and protect a quiet block in the room. Short town errands or browsing can stay optional; do not turn them into an all-weather attraction promise. Choose any outing around the group’s tolerance for transfers and wet clothing.

Treat the hotel pool as a guest option

Harraseeket and Hilton Garden Inn have indoor pools. Confirm opening, guest rules and supervision requirements before planning a swim; do not assume a hotel pool offers public day access.

Plan B: one Portland museum, with a transfer

Choose CMTM for exploratory play or PMA for a short art visit if those interests fit your family. The museums are in Portland, at Thompson’s Point and Congress Square respectively. Allow a separate journey from your Freeport room without assuming a measured drive time.

The Monday and admission checks

PMA lists Monday closure. CMTM says advance museum tickets are available but not required, with theatre ticketing presented separately. Check actual dates and access needs before setting out; a wet forecast does not ensure indoor capacity.

Choose tomorrow’s plan after the rest

If a local outdoor day has been postponed, leave it movable rather than squeezing it into tonight. A five-day stay can absorb a weather change more easily when every morning has not already been promised.

Turn the choice into a plan

If a city excursion is the right choice, read the Portland rain guide and the detailed children’s museum or art museum profile before leaving.

If staying local is better, keep the outing brief and leave the afternoon open. Dry clothing, a predictable meal and somewhere to rest often do more for a wet day than a longer list of attractions. Check the actual guest pool arrangements with Harraseeket or Hilton Garden Inn, rather than assuming public access or guaranteed operation.

Use the five-day Freeport sequence as a set of movable days. A single outdoor day can move to better conditions without adding a second base.
